Draw a well-labelled diagram of mitochondrion.
GeneralClass 12AllAnswered 27 Mar 2026
Answer
[Refer to diagram in PDF showing]:
- Outer membrane (smooth, permeable)
- Inner membrane (cristae - infoldings)
- Inter-membrane space (between membranes)
- Cristae (shelf-like projections)
- Matrix (inner fluid compartment)
Additional labels should include:
- ATP synthase (on cristae)
- Circular DNA (in matrix)
- 70S ribosomes (in matrix)
Key structural features:
- Double membrane system
- Cristae increase surface area ~5-fold for ETC
- Matrix enzymes for Krebs cycle
- Size: 0.5–1.0 µm diameter, 1–4 µm length
