Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many electrons are passed to each carrier NAD+ molecule to produce NADH in glycolysis?
A
2
B
8
C
5
D
4
Explanation: 

Detailed explanation-1: -To start, two electrons are carried to the first complex aboard NADH. This complex, labeled I, is composed of flavin mononucleotide (FMN) and an iron-sulfur (Fe-S)-containing protein.

Detailed explanation-2: -In glycolysis, 3-phosphoglyceraldehyde (PGAL) is oxidized to 1, 3-bisphosphoglycerate, which results in the production of 2 NADH molecules (BPGA).

Detailed explanation-3: -NADH produces the following amount of ATP: Glycolysis: By oxidative phosphorylation, 2 NADH generates 6 ATP. Reaction to Transition: 2 NADH generates 6 ATP.

Detailed explanation-4: -1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.

Detailed explanation-5: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
