Oxidative phosphorylation definition
Oxidative phosphorylation definition
Final stage of aerobic respiration; energy from electrons produces ATP
ATP yield from oxidative phosphorylation per glucose
ATP yield from oxidative phosphorylation per glucose
32-34 ATP molecules
Location of oxidative phosphorylation
Location of oxidative phosphorylation
Mitochondria (inner membrane)
Function of cristae in mitochondria
Function of cristae in mitochondria
Increase surface area for electron transport chain & ATP synthase
Role of reduced NAD and reduced FAD
Role of reduced NAD and reduced FAD
Donate electrons to first carrier in electron transfer chain
Function of ATP synthase
Function of ATP synthase
Channel for protons; synthesises ATP from ADP & phosphate
Final electron acceptor in electron transfer chain
Final electron acceptor in electron transfer chain
Oxygen
Advantage of staged energy release
Advantage of staged energy release
Less energy lost as heat; more captured to make ATP
Energy yield of lipids vs carbohydrates
Energy yield of lipids vs carbohydrates
Lipids release more than double the energy per gram
Entry points for protein respiration products
Entry points for protein respiration products
3-carbon to pyruvate; 4-5 carbon to Krebs cycle
