Question

how many net atp molecules are made in glycolysis? multiple choice 1 2

Explanation:

In glycolysis, 2 ATP molecules are used in the energy - investment phase (to phosphorylate glucose and then phosphorylate fructose - 6 - phosphate), and 4 ATP molecules are produced in the energy - payoff phase (through substrate - level phosphorylation). To find the net ATP production, we calculate the difference between the ATP produced and the ATP consumed. So, the net ATP production is $4 - 2=2$.

Answer:

2 (the option with "2" as the choice)
