Question

1. during glycolysis, how many atp molecules are produced?

○ 2
○ 4
○ 32
○ 36

Explanation:

Glycolysis is the first stage of cellular respiration. In glycolysis, 2 ATP molecules are consumed initially (to convert glucose to fructose - 1,6 - bisphosphate). Then, through substrate - level phosphorylation, 4 ATP molecules are produced. But when we calculate the net ATP production (total produced - total consumed), we have \(4 - 2=2\) ATP molecules.

Answer:

2
