Question

How does the mitochondria generate ATP?

Answer 1

Mitochondria: Mitochondria is a cell organ that is called the powerhouse of the cell. Here energy is generated in form of ATP.

ATP generation:

1. In the mitochondria, NADPH₂ and FADH₂ are produced during the Kreb cycle
2. NADPH₂ and FADH₂ release H⁺ and electrons enter in Electron transport system (ETS).
3. Electrons from these both molecules are given to the ultimate electron acceptor which is oxygen.
4. The electrons pass through different electron carrier complexes of ETS.
5. Now H⁺ ions are released in the inner mitochondrial space.
6. Now the H⁺ ions gradient is created across the inner membrane.
7. ATP synthetase enzyme becomes active and ATP is synthesized. This is called oxidative phosphorylation.
