WebMay 25, 2024 · Plants need water to make NADPH. This water is broken apart to release electrons (negatively charged subatomic particles). When water is broken it also creates oxygen, a gas that we all breathe. The electrons must travel through special proteins stuck in the thylakoid membrane. WebVideo transcript. A couple of videos ago, we saw that in classic C-3 photosynthesis-- and once again it's called C-3 because the first time that carbon dioxide is fixed, it's fixed into a 3-carbon molecule. But we saw the problem with C-3 photosynthesis is that the enzyme that does the carbon fixation, it can also react with oxygen.

WebMay 4, 2024 · CAM plants take in CO 2 through their open stomata (they tend to have reduced numbers of them). The CO 2 joins with PEP to form the four-carbon oxaloacetic acid. This is converted to four-carbon malic acid that accumulates during the night in the central vacuole of the cells. WebCAM plants are known for their capacity to fix carbon dioxide at night, using PEP carboxylase as the primary carboxylating enzyme and the accumulation of malate (which is made by the enzyme malate dehydrogenase) in the large vacuoles of their cells.

WebCAM Photosynthesis is for Plants Adapted to Dry Environments Contributors and Attributions The enzyme RuBisCO needs a high CO 2 environment to function efficiently. If the ratio of oxygen to CO 2 gets too high, RuBisCO will bind oxygen instead and waste energy in the process.

WebC4 photosynthesis requires the integrated functioning of mesophyll and bundle-sheath cells of leaves and is characterized by a CO2 concentrating mechanism that allows Rubisco, located in the bundle-sheath cells, to function at high CO2 concentrations.
