Question

question 18 (1 point)
____ atp are invested at the beginning of glycolysis to produce a total of ____ atp by the end.

○ 2, 4
○ 4, 2
○ 2, 2
○ 4, 4

Explanation:

Glycolysis is the process of breaking down glucose. At the start, 2 ATP molecules are used (invested) to initiate the process. By the end of glycolysis, a total of 4 ATP molecules are produced (through substrate - level phosphorylation). So we need to find the option where the first number is 2 (ATP invested) and the second number is 4 (ATP produced).

Answer:

A. 2, 4
