Biomed Academy Plans Cellular Respiration Unit Plan AP Content Standards-‐2.A.2 • Energy-‐related pathways in biological systems are sequential and may be entered at multiple points in the pathway. ❏ Krebs, glycolysis, Calvin, fermentation • • • ❏ Cellular respiration in eukaryotes involves a series of coordinated enzyme-‐ catalyzed reactions that harvest free energy from simple carbohydrates. o ❏ Glycolysis o ❏ Redox o ❏ Pyruvate o ❏ Krebs cycle (substrate level phosphorylation) ❏ The electron transport chain captures free energy from electrons in a series of coupled reactions that establish an electrochemical gradient across membranes. o ❏ Chemiosmosis/Proton Gradient o ❏ ATP Synthase o ❏ Compare mitochondria to prokaryotes o ❏ Decoupling oxidative phosphorylation from electron transport for thermoregulation ❏ Free energy becomes available for metabolism by the conversion of ADP → ATP, which is coupled to many steps in metabolic pathways.
