Question

How do the mitochondria use chemiosmotic gradient?

Answer 1

Mitochondria:

1. Mitochondria is a double membrane-bound eukaryotic cell organelle that generates ATP molecules.
2. The generation of ATP molecules is referred to as oxidative phosphorylation as energy molecules are generated by the oxidation of intermediary molecules.
3. The movement of ions via the semipermeable membrane powered by an electrochemical gradient is referred to as chemiosmosis.
4. This is a key phenomenon that occurs in mitochondria for the formation of ATP molecules by hydrogen ion transfer.
5. ATP synthase is involved in chemiosmosis and allows protons to pass via the membranes.
6. The final step of cellular respiration is conducted in the mitochondria.
7. NADH and FADH₂ molecules generated by the Krebs cycle help provide electrons to the electron transport chain and generates a proton gradient across the mitochondrial membranes.
