It is the correct location of ATP synthase in mitochondria:
Correct answer: B. Inner mitochondrial membrane
- A. Mitochondrial matrix
- B. Inner mitochondrial membrane
- C. Outer mitochondrial membrane
- D. Intermembrane space
Explanation
ATP synthase is located in the inner mitochondrial membrane, where it plays a crucial role in ATP production through a process known as chemiosmosis. As protons are pumped into the intermembrane space during the electron transport chain, they create a gradient that drives protons back into the matrix through ATP synthase, resulting in the synthesis of ATP from ADP and inorganic phosphate. The other options are incorrect because:Mitochondrial matrix: This area is involved in the Krebs cycle but does not house ATP synthase.Outer mitochondrial membrane: This membrane serves a different function related to transport and does not contain ATP synthase.Intermembrane space: While crucial for proton accumulation, it does not contain ATP synthase itself, but rather is the location of proton concentration.
