Which of the following acts as an electron carrier in cellular respiration? Select one: a. NAD+ b. pyruvic acid c. ADP d. ATP

Option A) NAD+

Explanation:

NAD+, also known as Nicotinamide adenine dinucleotide, is one of the known reducing equivalents.

It helps in carrying of electrons as hydrogen ions, thus becoming NADH, and then moving to the electron transport system in mitochondria of cells for the purpose of generating energy during respiration.

The answer is NAD+ because in cellular respiration there are two electron carriers which are NAD+ and FAD which carries the electrons.
