Question

Key Event 1: Chemical energy is invested. Key Event 2: High-energy electrons stored in bonds are released and transferred with protons to available electron carriers. Key Event 3: ATP is made by phosphorylation. During glycolysis, how many NADH molecules are produced per glucose molecule? Two Four One

Answer 1

Answer:

During Glycolysis 2 molecules of NADH are formed.

Explanation:

When the glycolytic intermediate glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate by the catalytic activity of glyceraldehyde -3-phosphate dehydrogenase at that time 2 molecules of NAD+ undergo reduction to form 2 molecules of NADH.

   The so formed NADH enters into the electron transport chain to generate ATP.
