Pond Weed Investigation

The effect of temperature on the rate of photosynthesis in Canadian Pondweed Elodea sp. In this investigation I plan to investigate how temperature effects the rate of photosynthesis in Canadian pond weed, this will be achieved by comparing the amount of oxygen produced by the pondweed at different temperatures. It will be a fair test and my only independent variable will be the different temperatures of water the pondweed will be submerged in. I am …

…temperature speeds up the movement of the substrate molecules, so that when they collide with the enzyme they have more energy and are more likely to bind to the active site.' Pickering, W.R. (2000). Complete Biology. Oxford University Press. Oxford. The reason for the rate dropping quickly after the peak is that, 'lose their three-dimensional shape and can no longer bind to their substrate.' Pickering, W.R. (2000). Complete Biology.
