Question

when performing vigorous exercise, what type of fermentation can your muscle cells undergo to continue producing atp in the absence of oxygen?
○ lactic acid fermentation
○ alcoholic fermentation

what gas is produced during alcoholic fermentation? (hint- it is what helps the bread dough to rise)
○ oxygen
○ glucose
○ carbon dioxide
○ ethanol

Explanation:

• For the first question: In the absence of oxygen, muscle cells undergo lactic acid fermentation to produce ATP. Alcoholic fermentation occurs in yeast and some bacteria, not in human muscle cells.
• For the second question: During alcoholic fermentation, carbon dioxide is produced. This gas causes bread dough to rise. Oxygen is not produced in alcoholic fermentation. Glucose is the starting substrate, not a gas product. Ethanol is a liquid product, not a gas that helps dough rise.

Answer:

• First question: lactic acid fermentation
• Second question: carbon dioxide
