  24. Chapter 10Photosynthesis CO2 H2O ETC NADH ETC Calvin cycle PS I ATP PS II H+ O2 glucose

  25. Chapter 10Photosynthesis Photo System II: • photon • energizes light harvesting complex • energizes P680 chlorophyll • releases e- to primary acceptor • water is split to replace e-, releasing H+ • e- is passed to ETC (Pq, cytochromes, Pc) • ETC makes ATP and brings in more H+.

  26. Chapter 10Photosynthesis Photo System I: • photon • energizes light harvesting complex • energizes P700 chlorophyll • releases e- to primary acceptor • ETC replaces e- • e- is passed to next ETC (ferredoxin) • NADP+ reductase makes NADPH.
