Net outcomes of
•
•
•
•
•
Oxidative phosphorylation (shuttles)
Fatty acid catabolism
Nitrogen catabolism
Light reactions of photosynthesis
Calvin cycle
Structures to know
• All amino acids
• (deoxy)ribonucleosides and
(deoxy)ribonucleotides
• Carbamoyl phosphate and urea
• Pyruvate, oxaloacetate, a-ketoglutarate
• PRPP
Metabolic Pathways/Reactions
• Know these reactions/pathways (not arrow
mechanisms)
– Beta oxidation
– PLP-mediated transamination
– Formation of carbamoyl phosphate
– Catabolism of amino acids covered in lecture
– Basic hydrolysis and RNase-catalyzed hydrolysis of
RNA
Protonmotive Force
• NADH + H+ + ½ O2  NAD+ + H2O + 10 H+ pumped
• succinate + ½ O2  fumarate + H2O + 6 H+ pumped
Photosynthesis: Net Reaction
2 H2O + 4 NADP+ + 8 photons  O2 + 4 NADPH
Proton Gradient
• For every ONE O2
– 4 e- passed
– 8 photons absorb
– 12 H+ pumped
• In plants, 12 H+
required to turn
ATP synthase
– 3 ATP made
• Quantum yield is
3 ATP/8 photons
or ATP/2.7 photon
