Questions & Step-by-Step Solutions
Which of the following statements about oxidative phosphorylation is true?
Step 1: Understand what oxidative phosphorylation is. It is a process that occurs in the mitochondria of cells to produce ATP, the energy currency of the cell.
Step 2: Learn about the electron transport chain (ETC). This is a series of proteins in the inner mitochondrial membrane that transfer electrons.
Step 3: Know that during the ETC, electrons are passed along the chain and energy is released, which is used to pump protons (H+) across the membrane.
Step 4: Recognize that oxygen plays a crucial role in this process. It is the final electron acceptor at the end of the electron transport chain.
Step 5: Conclude that without oxygen, the electron transport chain cannot function properly, and ATP production would be significantly reduced.
