Problem : Which of the following processes does not occur in the mitochondriabiology/cellstructure/mitochondria?

The citric acid cycle
Electron transport chain
Oxidative phosphorylation


Problem : Label the indicated structures on the following diagram of a mitochondria.

Figure %: Mitochondria.

1. Matrix 2. Intermembrane space 3. Innermembrane 4. Outer membrane.

Problem : Where in the mitochondria does oxidative phoshorylation take place?

In the matrix space.

Problem : What molecules are allowed to freely cross the inner mitochondrial membrane?

Only water, carbon dioxide, and oxygen.

Problem : How do molecules that cannot freely cross the inner mitochondrial membrane enter the matrix space to participate in the citric acid cycle and oxidative phosphorylation?

They are transported across by specific transporter proteins.
