Question

fill in the blank question the p/o ratio takes into account the fact that in the electron transport chain, there are protons pumped across the membrane per nadh and protons pumped across the membrane per fadh₂

Explanation:

In the electron - transport chain, for each NADH, 10 protons are pumped across the membrane and for each FADH₂, 6 protons are pumped across the membrane. This is based on the known stoichiometry of the electron - transport chain complexes and their proton - pumping capabilities.

Answer:

10; 6
