Kreb’s Cycle

Electron Transport Chain/ Oxidative Phosphorylation

Details of Cellular Respiration


Figure 9.9 A closer look at glycolysis: energy investment phase (Layer 1)


Figure 9.9 A closer look at glycolysis: energy investment phase (Layer 2)


Figure 9.9 A closer look at glycolysis: energy payoff phase (Layer 3)


Figure 9.9 A closer look at glycolysis: energy payoff phase (Layer 4)


Substrate-level phosphorylation


Figure 9.8 The energy input and output of glycolysis


Conversion of pyruvate to acetyl CoA, the junction between glycolysis and the Krebs cycle


Krebs cycle:


Figure 9.11 A closer look at the Krebs cycle (Layer 2)


Figure 9.11 A closer look at the Krebs cycle (Layer 3)


Figure 9.11 A closer look at the Krebs cycle (Layer 4)


Figure 9.12 A summary of the Krebs cycle


Free-energy change during electron transport chain


ATP synthase, a molecular mill


Chemiosmosis couples the electron transport chain to ATP synthesis:


Figure 9.16 Review: how each molecule of glucose yields many ATP molecules during cellular respiration
