Which structural feature of mitochondria increases the surface area for oxidative phosphorylation?

• Intermembrane space

• Double membrane

• Cristae

• Matrix

Answer explanation

The structural feature of mitochondria that increases the surface area for oxidative phosphorylation is the cristae, which are folds in the inner membrane where the electron transport chain and ATP synthesis occur.

What is the primary source of ATP in anaerobic conditions?

• Krebs cycle

• Electron transport chain

• Glycolysis

• Oxidative phosphorylation

Answer explanation

In anaerobic conditions, glycolysis is the primary source of ATP as it does not require oxygen to produce ATP through the breakdown of glucose.

What is the role of NADH in the electron transport chain?

• To carry electrons

• To generate oxygen

• To produce glucose

• To inhibit enzymes

Answer explanation

NADH's role in the electron transport chain is to carry electrons, which are then used to generate ATP through a series of redox reactions.
