the two molecules of pyruvate are completely degraded in krebs cycle to form hoe many molecules of ATP, NADH2, &FADH2 respectively

1. 3,4,5
2. 5,4,3
3. 2,8,2
4. 8,2,2

Hello Student
Correct answer is 1) 3,4,5
complete oxidation of one molecule of pyruvate in Kreb’s cycle can be represented as : –
Pyruvic+ 4NAD⁺+ FAD + 2H₂O+ADP + Pi
3CO₂+4NADH + 4H⁺+ FADH₂+ATP
SO, in complete oxidation of two molecules of pyruva, 2 molecules ofATP, 8 NADH₂and 2FADH₂are obtained.
