      The first product in the cycle has 4 carbons. PEP is a 4-carbon molecule. If C4 photosynthesis prevents photorespiration, why haven't all plants evolved to use the C4 pathway? All plants will evolve to be C4 in time. C4 produces some toxic byproducts. C4 is not advantageous in all climates. Only some plants use C4 photosynthesis.

      During photorespiration, CO2 is a product of photosynthesis, instead of O2. Ammonia (NH3) will shuttle H+ across a membrane from the more acidic side to the more basic side. This happens because NH3 is protonated under acidic conditions (NH3 + H+ ( NH4+), then can freely diffuse across the membrane, and then is deprotonated under the more alkaline side (NH4+ ( NH3 + H+).

      Photorespiration can drain away as much as 50% of the carbon fixed by the Calvin cycle on a hot, dry day. Certain plant species have evolved alternate modes of carbon fixation to minimize photorespiration. C4 plants first fix CO2 in a four-carbon compound. Several thousand plants, including sugarcane and corn, use this pathway.

      Jun 04, 2015 · Oxygen can also attach to the active site of rubisco and then the enzyme catalyses a process called photorespiration, a process involving oxygen as a substrate and carbon dioxide as a product. When photorespiration is occurring, CO2 is not being fixed. Photorespiration is a waste of ATP and does results in the synthesis of less GP and TP.

      Photorespiration may be an evolutionary relic from the time when there was little O2 in the atmosphere and the ability of rubisco to distinguish between O2 and CO2 was not critical. Now, in our oxygen-rich atmosphere, photorespiration seems to be an agricultural liability. a. in the bundle-sheath cells. b.
