Which molecule is known as the 'mobile electron carrier' that is reduced during glycolysis and carries electrons to the ETC in aerobic respiration?
Show answer and explanation
Correct answer: NAD+
NAD+ (Nicotinamide Adenine Dinucleotide) acts as an oxidizing agent in glycolysis, picking up two electrons and a proton to become NADH. In aerobic conditions, this NADH is then shuttled toward the mitochondria for oxidative phosphorylation.
