A. Citric acid cycle → Mitochondrial matrix (II):
The citric acid (Krebs) cycle occurs in the mitochondrial matrix where enzymes for the cycle are located.

B. Glycolysis → Cytoplasm (I):
Glycolysis takes place in the cytoplasm and breaks down glucose into pyruvate.

C. Electron transport system → Inner mitochondrial membrane (IV):
The ETS (electron transport chain) is embedded in the inner mitochondrial membrane.

D. Proton gradient → Intermembrane space (III):
During electron transport, protons (H⁺) are pumped into the intermembrane space, creating a proton gradient used for ATP synthesis.
