What is the job of the protons (H+) in the ETC?

(A) Pass through the proteins to pump electrons through the ETC

(B) To combine with water as water is a byproduct of photosynthesis.

(C) Capture the energy of the sun.

(D) Pass through ATP synthase to create synthase.

Answer:

The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP. Hope this helps!
