H carbon dioxide + ethanol [3] [3] State the name of the microorganiom wood in brood making and the group of organismo​

Answers

Answer 1

a.  The production of carbon dioxide is important in bread-making because it is responsible for the rising of the dough and the formation of air pockets in the bread.

b.   The process occurring at G is fermentation, specifically alcoholic fermentation

c. The changes at G are caused by the activity of yeast or other microorganisms present in the dough.

d.  The microorganism involved in bread-making is yeast.

How do we explain?

a. Because it causes the dough to rise and the creation of air pockets in the bread, carbon dioxide production is crucial while baking bread. Through the process of fermentation, which involves the breakdown of the dough's carbohydrates by yeast or other microbes, carbon dioxide is created as a byproduct. The dough expands as a result of the trapped carbon dioxide gas, giving the baked bread its light and airy quality.

(b) The process occurring at G is fermentation in particular  alcoholic fermentation where the yeast or other microorganisms metabolize the sugars in the dough and produce carbon dioxide and ethanol as byproducts.

The process occurring at H is the conversion of starch into maltose and glucose.

(c) These microorganisms uses the sugars in the dough as a source of energy and produce carbon dioxide and ethanol as metabolic byproducts. The carbon dioxide is responsible for the rising of the dough, while the ethanol evaporates during baking.

(d) The microorganism involved in bread-making is yeast and we know Yeast belongs to the group of organisms called fungi.
