2The process by which green plants use the energy of the sunlight to produce sugars (carbohydrates)
31) Light Dependent Reaction (produces energy) Reactions require direct involvement of lightOccurs at chloroplastsi. Chlorophyll is main pigment of green plantsii. Absorbs blue/red regions of spectrumiii. Reflects green
4Produce ATPProduce high energy electrons carried by NADP+Provide energy to make carbohydrates (sugars)!!!
5Energy will be used to…Produce NADPHSplit waterEtc….
62) Light Independent Reaction (makes sugars) a. Does not directly involve lighti. Can occur in the light or darkb. ATP and NADPH enter these reactionsc. Convert energy from ATP and NADPH into a form that can be storedConverts carbon dioxide and water into glucose
7These reactions: Produces energy rich sugars Removes CO2 from the atmosphere6 turns = 1 sugar molecule
8Formula for photosynthesis 6CO2 + 6H2O C6H12O6 + 6O2sunlight
9Importance of photosynthesis Light energy converted to chemical energy
