Question:
What is the role of NAD+ in cellular respiration?
It functions as an enzyme.
It is a nucleotide source for ATP synthesis.
It is the final electron acceptor for anaerobic respiration.
It functions as an electron carrier.
Solution:
NAD+ is the electron carrier that picks up electrons from other molecules and gets reduced to form NADH. It is then used as a reducing agent to donate these electrons. Thus, the correct answer is option D.
