Glycolysis: The Cytosolic Starting Point

Master the ten-step enzyme-catalyzed reactions that split glucose into two molecules of pyruvate. Understand how a small yield of ATP and NADH is generated without the need for oxygen.

The Krebs Cycle: High-Energy Harvest

Deep dive into the mitochondrial matrix where Acetyl-CoA is oxidized. Trace the path of carbon and the massive accumulation of NADH and FADH2 destined for the electron transport chain.

Oxidative Phosphorylation: ATP Synthesis

The final stage occurs across the inner mitochondrial membrane. Explore how the proton gradient drives ATP synthase to produce the energy required for life.
