Question

The place or site of oxidative phosphorylation in plant cell is

• A. Matrix of mitochondria
• B. Inner mitochondrial membrane
• C. Cytoplasm of cells
• D. Outer mitochondrial membrane

Hint:

Oxidative phosphorylation: Inner mitochondrial membrane.
ETC: Complexes I-IV.
ATP synthase: Complex V.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of oxidative phosphorylation.

Step 2: Detailed Explanation:
Oxidative phosphorylation occurs at the inner mitochondrial membrane.
The electron transport chain (ETC) and ATP synthase are located here.
The ETC creates a proton gradient across the inner membrane.
ATP synthase uses this gradient to produce ATP.
Matrix of mitochondria (A): Location of TCA cycle.
Cytoplasm (C): Location of glycolysis.
Outer mitochondrial membrane (D): Permeable to small molecules.
Thus, oxidative phosphorylation occurs at the inner mitochondrial membrane.

Step 3: Final Answer:
Thus, oxidative phosphorylation occurs at the inner mitochondrial membrane, which corresponds to option (B).
