An example
bio ch 7 photosynthesis light reactions in thylakoid, make atp + nadph, split water, O2 released calvin cycle in stroma uses atp nadph to fix co2 into sugar chlorophyll absorbs red and blue light
Photosynthesis (Chapter 7) Two stages - Light reactions: happen in the thylakoid membranes. Light energy splits water, which releases oxygen, and the energy is stored as ATP and NADPH. - Calvin cycle: happens in the stroma. It uses ATP and NADPH to turn CO2 into sugar. Key pigment - Chlorophyll absorbs mostly red and blue light. Quick check - Where does the oxygen come from? (Water, split in the light reactions) - What does the Calvin cycle need from the light reactions? (ATP and NADPH)
