Lesson 4: Oxidative Phosphorylation & Fermentation
Duration of Days: 3
Lesson Objective
Explain how the flow of protons through ATP Synthase drives the phosphorylation of ADP to produce the bulk of cellular ATP via chemiosmosis.
How would an uncoupling agent that allows protons to leak freely across the inner mitochondrial membrane affect ATP synthesis and core body temperature?
Why is the conversion of pyruvate into lactic acid or ethanol evolutionary essential for a cell when oxygen levels drop to zero?
3.3-Cellular Energy
3.6- Cellular Respiration
The final stage of respiration relies on an electron transport chain to maximize ATP production, dropping back to fermentation when oxygen is unavailable.
