Cellular Respiration
Last edited 2h ago
Aerobic respiration occurs in the mitochondria and produces 36-38 ATP…
The process unfolds in three main stages — each with characteristic substrates, enzymes, and energy yields. Below is a summary table for quick revision.
Key Points
- Stage one converts glucose into pyruvate.
- Stage two oxidises pyruvate inside the mitochondrial matrix.
- Stage three uses the electron transport chain to produce most ATP.
Tip
Memorise the net ATP yield per stage — it's a frequent exam question.
