Does Temperature Affect the Rate of Photosynthesis in Elodea - Free download as Word Doc (.doc /.docx), PDF File (.pdf), Text file (.txt) or read online for free. 2 Temperature and rate of photosynthesis Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light The dark reactions of photosynthesis are temperature dependent enzymatic processes. These reactions do have an optimum temperature. Photosynthesis by most plants. When the temperature rises the rate of photosynthesis rises also. There is an optimum temperature at which the rate of photosynthesis is maximum. Figure 14.9 Maize (a subtropical C 4 species) has a high optimum temperature (~30 °C) for CO 2 assimilation, while barley (a temperate C 3 species) has a lower, but. I was wondering whether or not photosynthesis has an ideal temperature range in regards to the chemical reactions that take place. Any information for that. Temperature response of photosynthesis in C3, C4, and CAM plants. The most typical case is a shift in the optimum temperature for photosynthesis. The optimum temperature for the enzyme polyphenol oxidase (PPO) is 40 degrees Celsius. This is the temperature at which the enzyme is most effective; like many oth. A BBC Bitesize secondary school revision resource for Higher Biology on photosynthesis. Photosynthesis exam skills. are nearer or at their optimum temperature.
