Biology coursework Investigating the rate of photosynthesis in Elodea canadensis INTRODUCTION AIM: The aim of this experiment is the effect of temperature on the rate of photosynthesis in Elodea canadensis. BACKGROUND KNOWLEDGE: As level: From Biology 1 (2000) JONES, FOSBERY + TAYLOR From AS level we learnt about enzyme structure and how products are formed. When carbon dioxide comes into contact with Rubisco it is converted to 2 X Glycerol-3-Phosphate. The yellow object is an enzyme. Enzyme's act as a catalyst to speed up the reaction and remains unchanged at the end of the process. With an enzyme present it increases the likelihood of a collision of the substrates to form a product. Enzymes are globular proteins and are coiled into three-dimensional shape, which have hydrophilic side chains on the outside to make sure they are soluble. In picture 1, we have a carbon dioxide molecule and a Rubisco molecule. These...
