For each molecule of glucose that undergoes cellular respiration, 36 molecules of ATP can be produced. This is due to the three steps of cellular respiration, which are glycolysis, the Krebs cycle, and the electron transport chain.

Glycolysis is the first step in cellular respiration and takes place in the cytoplasm of cells. It involves the breakdown of a single glucose molecule into two pyruvate molecules, as well as the production of two ATP molecules.

The Krebs cycle is the second step of cellular respiration and takes place in the matrix of the mitochondria. It involves the breakdown of pyruvate molecules, producing two molecules of Acetyl-CoA and four molecules of NADH. This step also produces one ATP molecule and three molecules of FADH2.

The Electron Transport Chain is the third step of cellular respiration and takes place in the inner mitochondrial membrane. It involves the breakdown of NADH and FADH2 molecules, and produces ATP molecules. For each molecule of NADH, three molecules of ATP are produced, and for each molecule of FADH2, two molecules of ATP are produced.

Therefore, for each molecule of glucose, 36 molecules of ATP can be produced.

1. **Order for Photosynthesis:** Photosynthesis is a complex process that requires several inputs for it to occur. Chlorophyll in the plant's leaves absorbs sunlight, which is then converted into energy. Water is taken up by the roots and transported to the leaves where it is used to create energy. Carbon dioxide is absorbed from the air and combined with the energy from sunlight and water to produce glucose, a type of sugar that is used as food by the plant.

2. **Outputs for Human Survival:** Plants play a crucial role in human survival, providing us with a variety of essential outputs. One of the most important outputs is oxygen. During photosynthesis, plants release oxygen into the air as a waste product. This oxygen is then breathed in by humans and other animals, allowing us to survive. In addition to oxygen, plants also produce a variety of foods that are essential for human survival, such as fruits, vegetables, and grains. These foods provide us with the nutrients we need to stay healthy, and they also form the basis of many of our diets.

3. **Chemosynthesis vs. Photosynthesis:** While photosynthetic producers are the most common type of producers, there are other organisms that carry out a similar process called chemosynthesis. Chemosynthetic producers are bacteria that use chemicals instead of sunlight to produce food. They are typically found in extreme environments, such as deep sea vents, where there is no sunlight available. Because they do not rely on sunlight, they can survive in areas where photosynthetic producers cannot. However, chemosynthetic producers are not a good food source for humans because they produce organic compounds that are not digestible by humans. Photosynthetic producers, on the other hand, are able to produce food that is digestible by humans and other animals, making them a more valuable food source for us.

Answer:

Explanation:

If we want to grow plants on another planet, we will need to provide them with the necessary conditions for photosynthesis to occur. This includes providing them with an adequate amount of light, water, and nutrients, as well as ensuring that the temperature and atmospheric conditions are suitable for their growth. If any of these conditions are not met, the plants may not be able to carry out photosynthesis effectively, which could impact their growth and survival.

Plants are a crucial source of food, oxygen, and other resources needed for human survival. They produce oxygen through photosynthesis, which is essential for human respiration. They also provide food in the form of fruits, vegetables, grains, and other plant-based products, which contain essential nutrients such as carbohydrates, proteins, vitamins, and minerals that are needed for human health. Additionally, plants play a crucial role in maintaining the Earth's ecosystem by regulating the carbon cycle and providing habitats for other organisms.

Producers that carry out chemosynthesis differ from photosynthetic producers in that they do not rely on light energy to produce organic compounds. Instead, they use energy from chemical reactions to convert inorganic compounds into organic compounds. Chemosynthetic producers are often found in extreme environments such as deep-sea hydrothermal vents or acidic soils, where the conditions are not suitable for photosynthesis. As a possible food source, chemosynthetic producers may have different nutritional profiles compared to photosynthetic producers, as they may contain different types and amounts of organic compounds. However, their potential as a food source for humans would depend on their availability and the feasibility of cultivating them for human consumption.

The correct statement(s) about absorption is (D) Amino acid transport is linked to sodium transport.

Amino acids are transported across the villus epithelium in the small intestine, and this process is linked to sodium transport.

Amino acids, not proteins, are absorbed; proteins rely on prior digestion to amino acids. Most absorption of amino acids occurs in the jejunum; there is a lesser contribution from the ileum.

Amino acids are absorbed by a co-transport mechanism with sodium ions. Both sodium ion and amino acid combine with a cell surface protein receptor.

There are different receptors for the groups: neutral amino acids, basic amino acids, acidic amino acids

In addition, certain amino acids may have there own specific transporter e.g. proline. The receptor then conveys both molecules to the inside of the cell.

The energy for this transport is derived from the concentration gradient for sodium across the cell membrane. Na-K ATPase transporters actively and continuously pump sodium ions outwards to maintain the gradient.

The direction of the reactions when the reactants are initially present in equimolar amounts are:

a. ATP+H₂0 yields ADP+ Pi - Favorable

b. ATP + glycerol yields glycerol 3 phosphate +ADP - Favorable

c. ATP +pyruvate yields phosphenolpyruvate +ADP - Unfavorable

d. ATP+ glucose yields glucose 6 phosphate +ADP - Unfavorable

The direction of each reaction can be determined by calculating the difference in free energy (∆G) between the reactants and products and comparing it to the standard free energy change (∆G°') at standard conditions (1 M concentrations and pH 7). The direction of a reaction is favorable when ∆G is negative (∆G < 0) and unfavorable when ∆G is positive (∆G > 0).

The equations for calculating ∆G are:

∆G = ∆G°' + RTln([products]/[reactants])

where R is the gas constant (8.314 J/mol•K), T is the temperature in Kelvin (usually 298 K), and [products] and [reactants] are the concentrations of the products and reactants, respectively.

Using the given data, calculate the standard free energy change (∆G°') for each reaction using the equation:

∆G°' = -RTln(K)

where K is the equilibrium constant for the reaction.

The values for ∆G°' are:

-30.5 kJ/mol for ATP + H2O -> ADP + Pi

-13.8 kJ/mol for ATP + glycerol -> glycerol 3-phosphate + ADP

+14.9 kJ/mol for ATP + pyruvate -> phosphoenolpyruvate + ADP

+13.8 kJ/mol for ATP + glucose -> glucose 6-phosphate + ADP

Now  calculate the ∆G for each reaction using the concentrations of the reactants and products, assuming they are initially present in equimolar amounts:

a. ATP + H₂O → ADP + Pi

∆G = ∆G°' + RTln([ADP][Pi]/[ATP]) = -30.5 kJ/mol + RTln(1) = -30.5 kJ/mol (Favorable)

b. ATP + glycerol → glycerol 3-phosphate + ADP

∆G = ∆G°' + RTln([glycerol 3-phosphate][ADP]/[ATP][glycerol]) = -13.8 kJ/mol + RTln(1) = -13.8 kJ/mol (Favorable)

c. ATP + pyruvate → phosphoenolpyruvate + ADP

∆G = ∆G°' + RTln([phosphoenolpyruvate][ADP]/[ATP][pyruvate]) = 14.9 kJ/mol + RTln(1) = 14.9 kJ/mol (Unfavorable)

d. ATP + glucose → glucose 6-phosphate + ADP

∆G = ∆G°' + RTln([glucose 6-phosphate][ADP]/[ATP][glucose]) = 13.8 kJ/mol + RTln(1) = 13.8 kJ/mol (Unfavorable)

Answer: Muscles are not capable of contracting.

Botulism is caused by a toxin produced by the bacterium Clostridium botulinum. This toxin prevents the release of the neurotransmitter acetylcholine (ACh) at the axon terminals. As a result, the signal from the neuron is not transmitted across the synapse, which prevents the muscle from responding to the signal. This can lead to muscle paralysis and cause flaccid paralysis in the affected muscles.

The lack of acetylcholine at the axon terminals prevents the muscles from receiving the signal from the neurons, so the muscle does not contract. This can lead to flaccid paralysis, where the muscle is not able to contract and is weak. In severe cases, this can lead to difficulty breathing, swallowing, and speaking. It can also cause vision problems, paralysis of the facial muscles, and death.

Other symptoms associated with botulism include drooping eyelids, blurred vision, double vision, slurred speech, and difficulty swallowing. It is important to seek medical attention immediately if any of these symptoms are present. Early diagnosis and treatment can help to reduce the severity of the symptoms and prevent any long-term complications.

To prevent botulism, it is important to cook food thoroughly and keep it refrigerated at all times. It is also important to keep canned food sealed, as the toxin can grow in improperly sealed cans.

Gluconeogenesis and glycolysis share many of the same enzymes because both processes involve breaking down glucose molecules and then building them back up. Specifically, the enzymes catalyze the breakdown of the bonds between atoms in the glucose molecule, and then form new bonds between the atoms to create a new molecule.

One reason why gluconeogenesis can use many of the same enzymes as glycolysis is because the two pathways are different yet closely interrelated; glycolysis is the breakdown of glucose while gluconeogenesis is the synthesis of glucose from noncarbohydrate sources such as pyruvate, lactate, glycerol, and some amino acids. Although these two pathways appear to be opposite of each other, they do share some of the same enzymes which could explain why gluconeogenesis is able to use many of the same enzymes as glycolysis.

Gluconeogenesis refers to the metabolic pathway that results in the generation of glucose from non-carbohydrate substrates such as lactate, pyruvate, glycerol, and glucogenic amino acids such as alanine and glutamine in vertebrates. This pathway is particularly significant in maintaining blood sugar levels during fasting and low-calorie diets. Gluconeogenesis takes place in the liver and kidneys and it is stimulated by hormonal and metabolic changes such as low blood sugar, high levels of glucagon, epinephrine, and cortisol.

The energy needed for this pathway is obtained from hydrolysis of ATP and GTP into ADP and GDP, which provides energy for the phosphorylation of glucose and fructose-6-phosphate.This process is known as “reversible reaction” and the same enzymes are used in both gluconeogenesis and glycolysis.
