Photosynthesis


 * Photosynthesis **

Photosynthesis occurs in two stages: the light reactions and the Calvin cycle (dark reactions).

[|Photosynthesis Animation] [|Calvin Cycle Tutorial]

//Light Reactions//
 * occurs in the thylakoid membranes
 * uses light energy to create ATP from ADP and phosphate
 * uses light energy to catalyze electron transfer from water to NADP+, which makes NADPH
 * when water is split, CO2 is released
 * sunlight = input
 * ATP & NADPH = output/product
 * CO2 = waste product

// Calvin Cycle (dark reactions) //
 * occurs in stroma of the chloroplast
 * electrons from NADPH and energy from ATP to reduce (split) CO2 and create glucose
 * CO2, NADPH, & ATP = input
 * glucose = output/product

//Chloroplast
