1) Locate the place in a plant cell where photosynthesis occurs.
2) Name the inputs of the light reactions in photosynthesis.
3) Describe the path and role they play in creating ATP and NADPH
The first step in photosynthesis is to break the water molecule (hydrolysis) in the presence of light energy and use the H+ to both create some ATP and put the H+ onto a carrier molecule, NADP. This step allows the Calvin Cycle to move forward and ultimately create the organic molecule glucose.
