What does “Aerobic respiration” actually mean in Respiration in Plants, and why does it matter for NEET?
the series of reactions – glycolysis, pyruvate oxidation, the Krebs cycle and oxidative phosphorylation – that use oxygen (directly or indirectly) to produce most ATP in mitochondria.
In simple words: aerobic respiration comprises glycolysis in the cytoplasm, conversion of pyruvate to acetyl‑CoA, the Krebs cycle in the mitochondrial matrix and the electron transport chain/oxidative phosphorylation in the inner mitochondrial membrane. These steps together, using oxygen either as the final electron acceptor or to regenerate NAD+, generate the bulk of ATP. Knowing this full sequence matters for NEET because questions often ask which parts are oxygen‑dependent or where each stage occurs.
Key point
Aerobic respiration
Common mistake
thinking Krebs cycle occurs in the cytoplasm.
Memory tip
the ATP-rich aerobic steps run inside the mitochondria.
