Explanation:

Step1: Glycolysis

Glycolysis is the first stage of cellular respiration. It takes place in the cytoplasm. The reactant is glucose. The products are 2 pyruvate molecules, 2 NADH molecules, and 2 ATP molecules (net gain). So, glycolysis yields NADH and ATP.

Step2: Pyruvate processing

Pyruvate processing occurs in the mitochondrial matrix. Each pyruvate molecule is converted into acetyl - CoA. During this process, one CO₂ molecule is released per pyruvate. So, pyruvate processing yields Acetyl CoA.

Step3: Citric acid cycle

The citric acid cycle also occurs in the mitochondrial matrix. Acetyl - CoA enters the cycle. The products of one turn of the citric acid cycle (per acetyl - CoA) are 2 CO₂ molecules, 3 NADH molecules, 1 FADH₂ molecule, and 1 ATP molecule (in the form of GTP which is converted to ATP). So, the citric acid cycle yields FADH₂.

Step4: Oxidative phosphorylation

Oxidative phosphorylation occurs in the inner mitochondrial membrane. It consists of the electron transport chain and ATP synthase. NADH and FADH₂ donate electrons to the electron transport chain. As electrons move through the chain, protons are pumped across the membrane, creating a proton gradient. ATP synthase uses this proton gradient to produce ATP. The final electron acceptor is oxygen, which combines with protons to form water. So, oxidative phosphorylation yields water.
