Answer 1

During respiration 38 ATP molecules per glucose molecule are produced in respiratory chain. 22 molecules of these 38 ATP molecules are produced from NADH₂/FADH₂ during Krebs cycle.

Explanation:

During the Krebs cycle, 6 NADH₂ and 2 FADH₂ molecules are produced. NADH₂ and F ADH₂ create 3 and 2 ATPs, respectively, when they enter the respiratory chain.

∴ 2 FADH₂ = 2 x 2 = 4 ATPs,

6 NADH₂ = 6 x 3 = 18 ATPs

18 + 4 = 22 total ATPs created.
