| 98595297 | Photolysis | Water is split by a manganese-containing enzyme Splitting using light | |
| 98595298 | Cytochrome | Iron-containing carrier protein also found in mitochondrial electron transport | |
| 98595299 | Cyclic Electron Flow | Produces only ATP Takes place in thylakoid membrane Not as efficient as non-cyclic because no NADPH is produced Water is not split; O2 not produced Evolutionary Leftover | |

| 98829705 | Reduction | The carbon molecules made in Carbon Fixation are reduced into to G3P that can be used to make glucose or perform other processes | |
| 98829707 | 1 Cycle of Calvin Cycle | 1 CO2 is fixed 3 ATP are used 2 NADPH are used 1 RuBP is regenerated 6 cycles needed to make 1 glucose molecule | |
| 98829709 | Photorespiration | occurs in light, consumes oxygen, and produces carbon dioxide Occurs in some plants on hot days when their stomatas are closed Wasteful process and evolutionary relic | |
| 98829711 | C4 Photosynthesis | A method that bypasses photorespiration Happens in corn, sugarcane, and other plants in hot, dry environments Moves from mesophyll to bundle-sheath cells | |
| 98829713 | CAM Photosynthesis | A method to bypass photorespiration Happens in water-storing plants such as cacti and pineapples At night stomata opens and carbon dioxide is taken in and is fixed into a variety of organic acids During the day, organic acids release CO2 and can be used for Calvin Cycle |
