The movement of protons during ATP synthesis in mitochondria takes place from outer chamber into inner chamber by F₀ part of oxysome present in the

Options

  1. Aouter mitochondrial membrane.
  2. Binner mitochondrial membrane.
  3. Couter mitochondrial chamber.
  4. Dinter-membrane space.

Correct answer

B. inner mitochondrial membrane.

Step-by-step solution

The oxysome or ATP synthase consists of two major components, F₀ and F₁ . The F₀ portion is an integral membrane protein complex embedded in the inner mitochondrial membrane. It forms a transmembrane channel that facilitates the diffusion of protons from the intermembrane space (outer chamber) back into the mitochondrial matrix (inner chamber). The F₁ portion is a peripheral membrane protein complex situated on the matrix side of the inner mitochondrial membrane, where it catalyzes the synthesis of ATP from ADP and
