Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: In the electron transport chain, electrons pass down a series of carriers, releasing energy used to pump protons.
Step 2: At the very end of the chain, oxygen accepts these electrons along with protons and is reduced to water.
Step 3: This is exactly what defines aerobic respiration, the requirement of oxygen as the final electron acceptor. Water is the product formed, not the acceptor itself.
