Cell Organelles: Mitochondria
Easybiology
Cristae increase the surface area for which mitochondrial process?
Select the correct option:
Solution
Incorrect! Answer:
Electron transport chain
- Mitochondrial Structure: Mitochondria have a double-membrane structure. The inner membrane is highly folded into finger-like projections called cristae.
- Purpose of Folding: Folding significantly increases the surface area available for chemical reactions.
- Electron Transport Chain (ETC): The enzymes and complexes associated with Oxidative Phosphorylation and the Electron Transport Chain are embedded in the inner mitochondrial membrane.
- ATP Production: A larger surface area (provided by cristae) allows for more ETC complexes and ATP synthase units to be present, maximizing the cell's ability to produce ATP.
