Solution
Correct 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.
This easy difficulty biology question is from the chapter cell structure and function, covering the topic of cell organelles: mitochondria. It appeared in the 2025 exam.
