Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following acts as an electron carrier in cellular respiration?
A
ATP
B
NADH
C
CO2
D
Glucose
Explanation: 

Detailed explanation-1: -NAD is the electron carrier that picks the electron from other molecules and gets reduced to form NADH.

Detailed explanation-2: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.

Detailed explanation-3: -NADH is the electron donor for the electron transport chain. The first complex to accept the donated electrons is NADH dehydrogenase.

Detailed explanation-4: -There are two types of electron carriers that are particularly important in cellular respiration: NAD +start superscript, plus, end superscript (nicotinamide adenine dinucleotide, shown below) and FAD (flavin adenine dinucleotide). Chemical structures of NAD+ and NADH.
