What are the stages of aerobic respiration?
Glycolysis → Link reaction → Krebs cycle → ETC + chemiosmosis. Keywords: metabolic pathway.
Where does each stage occur?
Glycolysis: cytoplasm * Link reaction: mitochondrial matrix * Krebs cycle: matrix * ETC: inner mitochondrial membrane Keywords: compartmentalization.
What is oxidative phosphorylation?
ATP generation using the ETC + chemiosmosis. Keywords: proton gradient, ATP synthase.
What is substrate-level phosphorylation?
Direct transfer of Pi to ADP during glycolysis + Krebs cycle. Keywords: direct phosphorylation.
What is the revised ATP yield per glucose?
About 32 ATP. Keywords: realistic yield.
What is the final electron acceptor in aerobic respiration?
Oxygen, forming H₂O. Keywords: terminal electron acceptor.
