For the two pyruvic acids that enter from glycolysis, the Krebs cycles will yield:
|
|
1 ATP, 2 NADH, and 1 FADH2
|
|
|
1 ATP, 2 NADH, and 2 FADH2
|
|
|
1 ATP, 3 NADH, and 1 FADH2
|
|
|
2 ATP, 8 NADH, and 2 FADH2
|
|
|
2 ATP, 4 NADH, and 2 FADH2
|
Explanation:
Detailed explanation-1: -In the Krebs cycle, two ATP, six NADH +H+, and two FADH2 were produced. A net of four ATPs was produced from glycolysis through the Krebs cycle.
Detailed explanation-2: -The number of ATP molecules produced in the Krebs cycle is 2.
Detailed explanation-3: -The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH2), as well as some ATP.
