Answer to Question 1

b

Answer to Question 2

The B vitamins, in general, serve as co-enzymes. The body's enzymes can break down glucose and produce ATP energy more efficiently if they have an ample supply of coenzymes. Niacin provides NAD that is a cofactor in the TCA (Krebs) cycle. This molecule is converted to NADH2 and later drives ATP production. Riboflavin, another B vitamin, produces FAD that is a cofactor in the TCA (Krebs) cycle. This molecule also helps drive ATP production in the electron transport system. Many athletes need a steady supply of ATP to power long term muscle contraction activity.
