Photosynthesis |
Reactions convertenergy from the sun to chemical bond energy of ATP |
|
|
ATP energy |
drives reactions that produce glucoseand other energy-rich compounds |
|
|
Organic Compounds |
arethe structural materials and energy stores of life |
|
|
Photoautotrophs |
produceorganic compounds by photosynthesis |
|
|
Sunlight Energy |
trappedand converted to chemical energy and ATP |
|
|
Photosynthesis reaction |
•12H20 + 6CO2---> 602 + C6H12O6 + 6H2O |
|
|
ATP |
suppliesenergy for reactions which synthesize glucose from CO2 and water |
|

Light-independentreactions occur in the |
|
|
LightDependent Reactions |
•Occurson thylakoid membrane •Pigmentsabsorb photon energy •Transferof electrons and hydrogen through electron transport system •Replacementelectrons flow to pigments•Electronflow may be cyclic or noncyclic |
|
|
•CyclicPathway |
–ATPforms –Electronscycle from and back to a Type 1 photosystem |
|
|
Non Cyclic Pathway |
-ATP and NADH form
-Electrons flow from water, through Type I and Type II photosystems, then to NADP + -Oxygen is a by- product |
|
|
•LightDependent |
•-Sunlightdrives ATP formation from ADP and Pi -Water is split -NADP picks upelectrons and hydrogen |
|
|
ElectromagneticEnergy |
•Visiblelight is 380-750nm |
|
|
•LightIndependent |
–ATPdonates energy –NADPHdonates hydrogen –CO2donates carbon and oxygen –Glucose(C6H12O6) is assembled |
|
|
NADH(Nicotinamide adenine dinucleotide) |
delivershydrogen andelectrons |
|
|
CalvinBenson Cycle |
•CarbonFixation •Unstablesix‐ carbon intermediate forms •Intermediatesplits to form two three‐ carbon molecules of phosphoglycerate •BuildingGlucose • -10 PGAL rearrange to regenerate RuBP |
