Explanation:

• Pyruvate oxidation: In eukaryotes, it occurs in the mitochondrial matrix. In prokaryotes, it happens in the cytoplasm. The starting molecule is pyruvate. The end - products are acetyl - CoA, NADH and CO₂.
• Kreb Cycle/ TCA cycle/ Citric Acid Cycle: In eukaryotes, it takes place in the mitochondrial matrix. In prokaryotes, it occurs in the cytoplasm. The starting molecule is acetyl - CoA. The end - products per turn are 3 NADH, 1 FADH₂, 1 ATP (or GTP) and 2 CO₂.
• Oxidative phosphorylation - Electron transport chain: In eukaryotes, it occurs in the inner mitochondrial membrane. In prokaryotes, it happens in the plasma membrane. The starting molecules are NADH and FADH₂. The end - product is ATP.
• Chemiosmosis: In eukaryotes, it occurs across the inner mitochondrial membrane. In prokaryotes, it occurs across the plasma membrane. The starting molecules are protons (H⁺) and ADP. The end - product is ATP, and the protein involved is ATP synthase.
