Question

In the electron transport system, a molecule of ATP is formed when an electron passes from: (A) Cytochrome-c to cytochrome-a (B) Cytochrome-a to cytochrome-c (C) Cytochrome-b to cytochrome-c1 (D) Cytochrome-c to cytochrome-b

Tardigrade Admin · Accepted Answer

In all, 3 ATP molecules are formed in the electron transfer system: i. First between NADH2 and FMN. ii. Second between cytochrome-b and cytochrome-c1 iii. Third between cytochrome-a and cytochrome-a3 <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/b-e0lq80bj4znf.png" />

Q. In the electron transport system, a molecule of ATP is formed when an electron passes from:

Cytochrome-c to cytochrome-a

Cytochrome-a to cytochrome-c

Cytochrome-b to cytochrome-c₁

Cytochrome-c to cytochrome-b

In all, 3 ATP molecules are formed in the electron transfer system:
i. First between NADH₂ and FMN.
ii. Second between cytochrome-b and cytochrome-c₁
iii. Third between cytochrome-a and cytochrome-a₃
