Whoo hoo! Spring Break has never looked so Close! (Just a week away!)

Summary of the Calvin Cycle:

Uses: CO2, NADPH, ATP

Produces: Glyceraldehyde -3- phosphate (a 3c sugar) , NADP+, ADP, Pi

• Carbon fixation occurs in the light. Both reactions (Light & Calvin Cycle) occur at the same time.

Summary of Photosynthesis:

1. Light Reactions

• occur inthe thylakoid membranes
• convert light energy to chemical energy in the form of NADPH & ATP.   - think that P in NADPH is in PHotosynthesis reactions.
• Split H2O, (Oxidize) & take e- to NADPH -- Oxygen is released as a byproduct.

2.) Calvin Cycle

• occurs in stroma of chloroplast

• uses ATP & NADPH of the light reactions to convert CO2 (gas) to the sugar glyceraldehyde-3-phosphate = 3C sugar.

  (3C sugar can be made into other compounds.)

• Returns ADP, Pi, NADP+ to light reactions to be reused.
