Solution

Analyze the Question

In glycolysis, the payoff phase (also known as the energy generation phase) involves the conversion of intermediates into end products while generating ATP and NADH.

Relevant Concepts

  1. Glycolysis Overview: Glycolysis is a series of enzymatic reactions that convert glucose into pyruvate, producing ATP and NADH in the process. The pathway can be divided into two main phases: the investment phase and the payoff phase.

  2. Payoff Phase: In the payoff phase, which occurs after the intermediate glyceraldehyde 3-phosphate (G3P) is formed from glucose, the following key steps take place:

    • G3P is converted to pyruvate.
    • ATP is generated through substrate-level phosphorylation.
    • NADH is produced from the oxidation of G3P.

Final Answer

The end product of the payoff phase of glycolysis is pyruvate.
