5 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
6 Produce ATPProduce high energy electrons carried by NADP+Provide energy to make carbohydrates (sugars)!!!
7 Energy will be used to…Produce NADPHSplit waterEtc….
8 The purpose of the light-dependent reactions is to… Make sugarsMake energy28 of 32
9 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
17 Metabolism Anabolic pathways Catabolic pathways All of the chemical reactions in a cellAnabolic pathwaysUse energy to build larger molecules from smaller moleculesPhotosynthesis: light energy from the sun is converted to chemical energy (builds glucose)Catabolic pathwaysRelease energy by breaking down larger molecules into smaller moleculesCellular Respiration: organic molecules (glucose) are broken down to release energy
