Step 1: Understand the process of cellular respiration, which is the metabolic pathway cells use to convert glucose into energy in the form of ATP.
Step 2: Recall the three main stages of cellular respiration: Glycolysis, Krebs cycle (also known as the citric acid cycle), and the Electron Transport Chain (ETC).
Step 3: Glycolysis occurs first in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.
Step 4: The Krebs cycle follows, taking place in the mitochondrial matrix. Pyruvate is further broken down, generating more NADH, FADH2, and a small amount of ATP.
Step 5: The Electron Transport Chain is the final stage, occurring in the inner mitochondrial membrane. NADH and FADH2 donate electrons to the chain, driving the production of a large amount of ATP through oxidative phosphorylation.
