2 pyruvate molecules
Explanation: Pyruvate is a product product of glycolysis.
Input: 2 NAD+ output: 2 NADPH
Input: glucose: output: 2 pyruvates
Input: 2 ATP (note: glycolysis has an energy investment phase and an energy payoff phase. it uses 2 ATP and produces 4 ATP. The net ATP is 2, making it an output aka product.)
