Here is a concise summary of the provided article on photosynthesis in C3 and C4 plants: Photosynthesis Model - C3 plants use the Farquhar et al. (1980) model, while C4 plants use the Collatz et al. (1992) model. - Leaf net photosynthesis is the minimum of three rates: Rubisco-limited (Ac), light-limited (Aj), and product-limited (Ap), minus leaf respiration (Rd). C3 Plant Photosynthesis - Ac depends on internal CO2 (ci), Vcmax, and Michaelis-Menten constants. - Aj depends on electron transport rate (Jx) and absorbed light (IPSII). - Ap is 3 times the triose phosphate utilization rate (Tp). C4 Plant Photosynthesis - Ac is simply Vcmax. - Aj varies with absorbed light (φ) and quantum efficiency (α). - Ap depends on ci and the PEP carboxylase-limited rate constant (kp). Temperature Dependence - Parameters like Vcmax, Jmax, Tp, Rd are adjusted for leaf temperature (Tv) using Arrhenius and high-temperature inhibition functions. - C4 plants use a different temperature response function. Acclimation - Vcmax and Jmax are allowed to acclimate to growth temperature (T10) by adjusting the entropy terms (ΔS). - The Jmax/Vcmax ratio at 25°C also decreases with warmer growth temperatures.
