Autotrophic vs heterotrophic
Light absorbance vs transmittance
Chlorophyll a and the reaction center
Accessory pigments role
Water, Oxygen, Carbon dioxide, NADPH2, ATP
Chloroplasts, thylakoids (grana), stroma
Photosystem II vs. I
Linear electron flow (linear photophosphorylation)
Cyclic electron flow
Electron Transport Chain …chemiosmosis…ATP synthase in the stroma
(outside the thYlakoids)
Photophosphorylation
Photosystem I only
Light reactions ( memorize inputs and outputs)
Photolysis
Source of oxygen?
Radio-labeled tracers
Dark Rxns (memorize inputs and outputs)
Carbon fixation
Rubisco
Photorespiration
PEP carboxylase
Organic acids
C3, C4, CAM plants (examples and why)
Stomata

Catabolic vs. anabolic
Oxidation vs. reduction
Potential energy of glucose, pyruvate, carbon dioxide, NAD+ vs NAD
4 steps to aerobic
Memorize inputs and outputs!
Anaerobic (glycolysis and fermentation)
Glycolysis (inputs and outputs) cytosol
Substrate level phosphorylation
Inefficient because only 2 ATPs via substrate level phosphorylation but NAD+
is recycled
Fermentation regenerates NAD+ so glycolysis can continue
Yeast (alcoholic) (loss of carbon dioxide)
Lactic acid (muscle cells) ….returned to the liver to be processed back to l.a.
Pyruvate oxidation and Acetyl Co-A
Krebs cycle ( memorize inputs and outputs)
Citrate/citric acid
NADH and FADH2 (ATPs per each)
Oxidative phosphorylation!!!!!!!!!!
Final electron acceptor
 Electron Transport Chain
 Chemiosmosis (H+ pumped out into the inner membrane space and rushes
back into the matrix via ATP synthase
 NADH and FADH2 are electron carriers to the ETC
 Proton-motive force
 Controlled by allosteric enzymes in glycolysis and citric acid cycle
Comparing P and R
Where do they each take place? (all cells vs, just photosynthetic cells)
How is chemiosmosis similar in P vs R? different?
Photophorylation in P vs oxidative phosphorylation in R
CR in prokaryotic vs, eukaryotic cells and evolutionary connection
