Question

In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are __________ when they provide the needed electrons or energy. a. Consumedb. Formed c. Degenerated d. Oxidized

Answer 1

a. Consumed

Step-by-step explanation:

Anabolic reactions mostly require the input of energy to form the complex molecules by binding the simpler ones together. Hydrolysis of ATP release the energy which is used during the anabolic reactions. Similarly, anabolic reactions mostly require an electron donor and NADH serves as the same. For example, glucose synthesis from CO2 is an anabolic pathway. It consumes the energy of ATP and uses NADPH as an electron donor. NADH is used during the synthesis of membrane lipids such as Plasmalogens.
