2 The process by which green plants use the energy of the sunlight to produce sugars (carbohydrates)
3 1) 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
4 Produce ATPProduce high energy electrons carried by NADP+Provide energy to make carbohydrates (sugars)!!!
5 Energy will be used to…Produce NADPHSplit waterEtc….
6 2) 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
7 These reactions: Produces energy rich sugars Removes CO2 from the atmosphere6 turns = 1 sugar molecule
8 Formula for photosynthesis 6CO2 + 6H2O C6H12O6 + 6O2sunlight
9 Importance of photosynthesis Light energy converted to chemical energy
