Why the vitamin niacin is a necessary component of nad, Biology

Assignment Help:

The vitamin niacin is a necessary component of NAD. Niacin can be consumed in food or manufactured in the body from tryptophan, an amino acid. How would a person's ability to break down glucose by glycolysis be affected if the person's diet were deficient in both niacin and tryptophan? Describe your answer.

Without niacin or the ability to make it, the person would be deficient in NAD. As NAD is used in Step 3 of glycolysis, glycolysis would be inhibited.
