[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
Yeast and bacteria can survive on glycolysis and fermentation pathways alone, while animals require aerobic pathways. Why is this true?
|
|
Yeast and bacteria do not need ATP
|
|
|
Yeast and bacteria have no access to glucose
|
|
|
Yeast and bacteria are unicellular and can survive on minimal ATP production, while complex multicellular organisms require much more ATP
|
|
|
Yeast and bacteria are autotrophs and make their own food, so the presence of mitochondria is irrelevant and ATP is not a necessity.

Explanation:
Detailed explanation-1: -When yeast cells are kept in an anaerobic environment (i.e., without oxygen), they switch to alcoholic fermentation to generate usable energy from food. Like lactic acid fermentation, alcoholic fermentation generates NAD+ so that glycolysis can continue to produce ATP.
Detailed explanation-2: -Advantages of Aerobic Respiration With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
