Generalized Arrhenius Function
Generalized Arrhenius Function
How a chemical reaction depends on temperature is often parameterized by the Arrhenius function (blue line). Enzyme-mediated reactions respond to temperature in a more complicated manner: high temperatures reduce the catalytic effect exerted by the enzymes (red line). The optimal temperature () is not always close to the temperature of enzyme denaturing. The temperature response of photosynthesis, for example, is often drawn as a bell-shaped curve (green line). This type of temperature response can be modeled with the generalized Arrhenius function, if .
