Question

Fermentation breaks down the glucose when no ___ is available in order to make some ATP. Two types are lactic acid and alcoholic fermentation.

Question 4 options:

oxygen


carbon dioxide


hydrogen


nitrogen

Answer 1

Fermentation breaks down the glucose when no oxygen is available in order to make some ATP, hence option a is correct.

What is lactic acid fermentation?

Glycolysis, the first step in fermentation, converts glucose into two pyruvate molecules, two ATP (net), and two NADH.

The constant breakdown of glucose to produce ATP during fermentation is made possible by the recycling of NADH to NAD+, to produce lactic acid and alcoholic fermentation.

Therefore, the fermentation's need for anaerobiosis is made easier by the carbon dioxide that is created in place of the air, hence option a is correct.
