Question

What is the advantage of having Complexes I, III, and IV associated with one another in the form of a respirasome?

a. It facilitates the energetically unfavorable electron transfer reactions carried out by Complexes I, III, and IV.
b. A respirasome composed of Complexes I, III, and IV allows the efficient transfer of electrons from to oxygen.
c. It enables the rapid transfer of electrons, thereby increasing the efficiency of proton pumping.
d. The respirasome allows and to interact directly with the inner mitochondrial membrane.

Answer 1

The correct answer is c. It enables the rapid transfer of electrons, thereby increasing the efficiency of proton pumping.

Step-by-step explanation:

Having three complexes will increase efficiency due to the fact that these complexes are connected, being more efficient in proton pumping.
