An example would be when the leaves change color in the fall. The chlorophyll breaks down and pigments in the leaves trap different colors.
This needs light. it takes place in the thylakoid membrane. it uses water. ATP and ADP are made and oxygen is made
Step 2 Calvin cycle
Does not need light. This takes place in the stroma of chloroplast. the first step is called carbon fixation where carbon dioxide molecules combined with carbon combounds to form a carbon molecule called 3 phosphoglycerate. Using energy from ATP and reduced power of NADPH the 3 phosphoglycerate goes through a series of reactions and are converted into 2 glyceraldehyce 3 - phosphate. When the 2 glyceraldehyce 3 phosphate are produced some combined to make glucose, while others return to the calvin cycle. This has to be done several times.
