Question

Q7). NAD+

A) is a coenzyme acceptor of phosphates.
B) is a coenzyme acceptor of electrons and a hydrogen ion.
C) is an electron source for biological oxidation reactions.
D) is used in both respiration and photosynthesis.

Answer 1

NAD+ is a coenzyme acceptor of electrons and a hydrogen ion. It acts as an electron acceptor during the enzymatic removal of hydrogen atoms and is used in biological oxidation reactions.

Step-by-step explanation:

NAD+ is a coenzyme acceptor of electrons and a hydrogen ion. It acts as an electron acceptor during the enzymatic removal of hydrogen atoms. NAD+ is the oxidized form of the molecule, while NADH is the reduced form after accepting two electrons and a proton. NAD+ is commonly used in biological oxidation reactions and plays a significant role in cellular energy metabolism.
