|---|
| Krantz anatomy | C4 anatomy |
| photorespiration | undoes what photosynthesis does! |
| Rubisco | ribulose biphosphate; catalyzes reaction of RuBP and CO2 |
| RuBP | 5-C sugar in Calvin Cycle |
| PGAL | 3-C product of the Calvin Cycle |
| CAM Pathway | crassulacean acid metabolism--cacti use this to conserve water |
| C4 pathway | used by tropical plants to avoid photorespiration |
| bundle sheath cells | sequester CO2 so photorespiration can be avoided |
| crab grass, corn, sugarcane | C4 plants |
| accessory pigments | carotene and xanthophylls |
| retinal | eye pigment that is a derivative of carotene |
| C3 Pathway | The Calvin Cycle or "dark reactions" |
| Thylakoid membrane | found in chloroplast |
| grana | stack of membranes found in chloroplast |
| reaction center | cluster of pigment molecules that collect photons of light |
| Photosystem I and II | reaction centers in the light reactions |
| Oldest Photosytem | Photosystem I |
| Reducing power | H+ ions and electrons |
