PPT-Factors affecting Enzymes

Specification Enzymes amp pH Each specific enzyme can only work over a particular range of pH Each enzyme has its own optimum pH where the rate of reaction is maximum The effects of pH on the rate of enzyme controlled reactions . Understanding:. Enzymes have an active site to which specific substrates bind. Enzyme catalysis involves molecular motion and the collision of substrates with the active site. Temperature, pH and substrate concentration affect the rate of activity of enzymes. Reactions. Most reactions take place in a number of steps which need to be carefully controlled if the cell is to function properly. Enzymes are the most important controllers of cellular reactions. Catalysts. Essential idea: Enzymes control the metabolism of the cell.. Above is just a small part of the IUBMB-. Sigma-Nicholson Metabolic Pathways Chart . aims to show all the metabolic pathways found in eukaryote cells. The chart in it's entirety shows how complex the chemicals reactions needed to support life in a single cell unit.
