About Lesson
Mitochondria
- Powerhouse of cells.
- Sphere, rod or filamentous body.
- 5 µm diameter and 7 µm in length
- Inner membrane has large infoldings called cristae and is site of oxidative phosphorylation and electron transport involved in ATP production.
- Central matrix is the site of Citric acid cycle and fatty acid breakdown.
Enzyme present: ATP synthetase, pyruvate dehydrogenase, Adenine nucleotide translocase, glyceral 3-phosphate dehydrogenase, succinate dehydrogenase, cytochrome c oxidase.
Function
- Oxidative phosphorylation
- Conserve energy for cellular respiration and urea cycle.
