Glycolysis
Location: Cytoplasm.
Process: Breaks down glucose into pyruvate.
Outputs: ATP and NADH.
The Link Reaction
Location: Mitochondria.
Process: Converts pyruvate to acetyl-CoA.
Outputs: NADH and carbon dioxide.
The Krebs Cycle
Location: Mitochondrial matrix.
Process: Processes acetyl-CoA.
Outputs: ATP, NADH, FADH2, and carbon dioxide.
Oxidative Phosphorylation
Location: Inner mitochondrial membrane.
Process: Electrons from NADH and FADH2 travel through the electron transport chain.
Outputs: ATP via ATP synthase driven by proton gradient.
