NADP+ ________ + _____ + _____ → ____________ 2 e- H+ _______= nicotinamide adenine dinucleotide phosphate
Photosynthesis consumed ____________________ involves a complex series of chemical reactions, in which the product of one reaction is _____________ by the next reaction. consumed Product Y Reaction 1 → Product → X Reaction 2 → A series of reactions linked in this way is referred to as a __________________________ biochemical pathway
Light-Dependent Reaction PHOTOSYNTHESIS oxygen Light & Water Light-Dependent Reaction ATP NADPH (CH2O)n Carbon Dioxide Light-Independent Reactions Calvin Cycle
Main Idea Ultimate Goal – to make sugar (glucose) Two-Step Reaction 1st step – Absorb energy from sun & capture it 1st as electrons, then as ATP 2nd step – use that ATP & the electrons to build sugar from CO2!
