Answer 1

The products of glycolysis include 2 ATPs (net), 2 pyruvates, and 2 NADHs; no FADH2, CO2, or acetyl CoA are produced. The energy from glucose is retained mostly in pyruvate and NADH.

Step-by-step explanation:

The products of glycolysis are 2 ATPs (net), 2 pyruvates, and 2 NADHs. Glycolysis starts with glucose and ends with the formation of pyruvate molecules, a process that uses 2 ATP molecules to generate a total of 4 ATP molecules but results in a net gain of only 2 ATP because 2 are consumed in the initial steps of glycolysis. These two pyruvates can enter the Krebs cycle for further processing, while the generated NADH molecules have the potential to create more ATP later in the mitochondria. No FADH2 is produced during glycolysis nor are any CO2 molecules or acetyl CoA, as these are products of subsequent stages of cellular respiration. After glycolysis, most of the energy of the original glucose molecule is retained in the pyruvate and stored in the NADH produced.
