Energy from ETC in Photosystem 2 transfers to Photosystem 1
ETC Energy Excites P700
Cyclic Electron Flow
The plant process switches to Cyclic Electron Flow when enough NADPH is made within the cell
The plant produces ATP
Ferredoxin

H2O
Primary Acceptor
Electron Transport Chain
ATP
Glycolysis occurs in the cytosol and Krebs Cycle occurs within the Mitochondria
Totals
10 NADH
4 ATP
Krebs Cycle (Energy Payoff)
2 FADH2
1 FADH2 per Acetyl CoA
6 NADH
3 NADH per Acetyl CoA
1 ATP per Acetyl CoA
2 Acetyl CoA
Enters Mitochondrion
Acetyl CoA
Pyruvate cannont enter Krebs Cycle
It is converted into Acetyl CoA by removing CO2 and transfering an electron with energy to NAD+ to make NADH.
Since 2 pyruvate are formed, 2 NADH are formed and 2 Acetyl CoA are made
Oxaloacetate
Acetyl CoA attaches to Oxaloacetate 1 at a time!!!
Produces the molecule Citrate
Isocitrate
Citrate is converted into Isocitrate by dehydration process.
Isocitrate loses energy to NAD+ to make NADH.
It also loses CO2.
Molecule becomes a-Ketoglutarate
Becomes oxidized, makes another NADH and loses another CO2.
Molecule becomes Succinyl CoA.
ATP Generation
The Co-A group is removed By the addition of a phosphate which is then removed to be added to GDP to make GTP which is then transfers it's phosphate to ADP to make ATP.
The remaining molecule after the production of ATP is Succinate which transfers 2 electrons to FAD to make FADH2 becoming Fumarate which gains water to become Malate which is unstable enough to oxidize and make another NADH to end/ start the cycle with another oxaloacetate.
Glycolysis (Energy Investment)
2 Pyruvate
4 ATP Used
Oxidation
Split: 2 (3) Carbon Sugars
Glucose
Reactant: 6 Carbon Glucose Sugar Molecule
Hexokinase
Hexokinase transfers a phosphate group from ATP to glucose, making it unstable (traps glucose in the cell)
Molecule becomes: Glucose 6-phosphate
Enters enzyme: Phosphogluco-isomerase
converts Glucose 6-phosphate to its isomer
Molecule becomes: Fructose 6-phosphate
Phosphofructokinase
Adds phosphate to Fructose 6-phosphate from ATP in the cell making it very unstable
(can be used for regulation)
Molecule becomes: Fructose 1,6-bisphosphate
Enters Adolase: Makes 2 molecules one of which is converted to be like the other forming 2 molecules of Glyceraldehyde 3-phosphate
Triose Phosphate Dehydrogenase
Enzyme oxidizes molecules transfering the 2 electrons to NAD+ to from 2 NADH (electron carrier: energy carrier)
and 2 H+ ions
Attaches a phsphate to make it unstable
Molecule becomes: 1,3-bisphosphogylerate
Phosphoglycerokinase
Enzyme uses the phosphates from previous molecule to make 2 ATP (substrate level phosphorylation)
A substrate (1,3-bisphophoglycerate) synthesized the production of ATP.
Molecule becomes: 3-Phosphoglycerate
Phosphoenol-Pyruvate(PEP)
3-Phosphoglycerate enters phosphoglyceromutase which moves the phosphate group around to make the molecule unstalbe
Molecule becomes: 2-phosphoglycerate
Enters enolase wich forms a double bond in the R - Group by extracting water making
Pohsphoenolpyruvate (PEP) Super unstable and HIGH Energy
PEP enters the enzyme Pyruvate Kinase which transfers a phosphate from PEP to ADP to make 2 ATP (Another Substrate Level Phosphorylation)
Final: 2 molecules of Pyruvate
4 ATP produced - 2 used: 2 ATP Yield
2 NADH Yield
2 Pyruvate
Fermentation
Pyruvate
Lactic Acid
2 Lactate
2 Pyruvate gain 2H+ ions from the 2 NADH made in Glycolysis to make 2 NAD+ and 2 Lactate
Alcohol
2 Ethanol
2 NADH
Both used to make Ethanol producing 2 NAD+
2 ATP
CO2
Pyruvate loses 2 CO2 to make 2 Acetaldehyde
Acetaldehyde
Acetaldehyde gains 2 H+ ions from the 2 NADH made in Glycolysis to produce 2 NAD+ and the 2 H+ions attach to the 2 Acetaldehyde to make 2 Ethanol
