Question 1

What basic steps occur in glycolysis? What are the reactants and products? What is meant by the terms ‘energy investment phase’ and ‘energy payoff phase’?

Answer 1

In glycolysis, 2 ATP molecules are used at the start of it to get the process started. Then high-energy electrons are passed to the electron carrier NAD+, forming two molecules of NADH, and 4 ATP are synthesized during glycolysis for a net gain of 2 ATP.
