Which mitochondrial structure is the location of oxidative phosphorylation?

• A. Outermembrane
• B. Intermembrane space
• C. Inner membrane
• D. Matrix

Answer: (C)

Verified step by step guidance

1. Understand the process of oxidative phosphorylation, which is the final stage of cellular respiration where ATP is produced using energy derived from electrons transferred through the electron transport chain.
2. Recognize that the electron transport chain is a series of protein complexes located in a specific part of the mitochondrion.
3. Identify the structure of the mitochondrion, which includes the outer membrane, intermembrane space, inner membrane, and matrix.
4. Recall that the electron transport chain and ATP synthase, the enzyme responsible for ATP production, are embedded in the inner membrane of the mitochondrion.
5. Conclude that the inner membrane is the site where oxidative phosphorylation occurs, as it houses the necessary components for the electron transport chain and ATP synthesis.
