If oxygen is not present what process will occur in yeast cells?
|
|
Alcoholic fermentation
|
|
|
Respiration
|
|
|
Photosynthesis
|
|
|
Lactic acid fermentation
|
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: -Now, yeast, just like humans or any other living organism, can actually ferment without oxygen for a short time. This is called anaerobic respiration and it can happen in the absence of oxygen.
