Lecture 14: Electron Transport Chain
Topic
Reading
Electron Transport Chain
oxidation/reduction in the mitochondrial membrane
NADH to NAD+ = oxidation
oxygen to water = reduction
coupled reaction yields 52 Kcal/mole
Multistep process - move electrons down energy hill
use cytochromes
Chemiosmotic Theory
pump protons (oxidation.reduction)
create potential energy gradient
ATP phosphorylation
yield
1 NADH yields 3ATP
1 FADH2 yields 2 ATP
