Final Answer:
The four basic stages of glucose oxidation in order from first to last are Glycolysis, Pyruvate Decarboxylation (Transition Reaction), Citric Acid Cycle (Krebs Cycle), and Electron Transport Chain with Oxidative Phosphorylation.
Step-by-step explanation:
The four basic stages of glucose oxidation in order from first to last are:
Glycolysis: Glucose is broken down into two molecules of pyruvate in the cytoplasm, producing a small amount of ATP and NADH.
Pyruvate Decarboxylation (Transition Reaction): Pyruvate is transported into the mitochondria and converted into acetyl CoA, releasing carbon dioxide.
Citric Acid Cycle (Krebs Cycle): Acetyl CoA enters the citric acid cycle in the mitochondria, generating NADH and FADH2 and releasing carbon dioxide.
Electron Transport Chain and Oxidative Phosphorylation:** NADH and FADH2 produced in the previous stages donate electrons to the electron transport chain, leading to the production of ATP through oxidative phosphorylation. Oxygen is the final electron acceptor, forming water.
