High photorespiration
WebUnder high temperature, high light, and the current CO2 concentration in the atmosphere, the C4 pathway is more efficient than C3 photosynthesis because it increases the CO2 concentration around the major CO2 fixing enzyme Rubisco. Thus the oxygenase reaction along with photorespiration is suppressed. WebApr 8, 2024 · Photorespiration in plants is thought to have risen over time and is the result of increasing levels of O2 in the atmosphere-the by-product of photosynthetic organisms themselves. The intended reaction is the addition of carbon dioxide to RuBP (carboxylation), which is a crucial step in the Calvin–Benson cycle.
