Which statements about the products of glycolysis is true? (check all that apply)?

These statements about the products of glycolysis are true:
1. ATP and NADH are the only high energy molecules produced by glycolysis.
2. A cell may either reduced or oxidized pyruvate depending on the cellular conditions.
Glycolysis is the process by which glucose molecules are broken down in the cell in the presence of oxygen in order to obtain energy. The products of glycolysis are 2 ATP, 2 NADH and 2 pyruvate molecules. The pyruvate formed can either by oxidized or reduced in the cell depending on whether oxygen is present or absent.

What does that mean you dum bum
