Question

Alcoholic fermentation

A: forms fewer ATP molecules than cellular respiration
B: uses oxygen and ATP molecules as reactants
C: occurs in the muscle cells of animals and humans
D: gives off carbon dioxide and NADH as products

Answer 1

A) Forms fewer ATP molecules than cellular respiration.

It usually forms 2ATP as opposed to 38ATP formed during cellular respiration.

Answer 2

The correct answer is: A) forms fewer ATP molecules than cellular respiration.

Step-by-step explanation:

Alcoholic fermentation is an anaerobic process (made in absence of oxygen) in which carbohydrates such as glucose and fructose are converted into cellular energy, with the production of ethanol and carbon dioxide as by-products. Alcoholic fermentation, however, only produces 2 ATP molecules as opposed to the 38 ATP molecules formed during cellular respiration.

Alcoholic fermentation is performed mostly by yeasts, and its products are used by humans in the making of alcoholic beverages such as beer and the cooking of bread.

Option B is incorrect because alcoholic fermentation is performed when there's no oxygen around, this makes it anaerobic.

Option C is false. There is fermentation occurring in the muscle cells of animals and humans but it's not alcoholic- it's lactic acid fermentation.

Option D is false as well because the end products are carbon dioxide and ethanol.
