PPT-Enzymes and Concentration

Lesson 16 Success Criteria Describe and explain the effect of enzyme concentration and substrate concentration on enzyme activity Starter Think pair share Effect of enzyme concentration on enzymes. Understanding:. Metabolic pathways consist of chains and cycles of enzyme-catalysed reactions. Enzymes lower the activation energy of the chemical reactions that they catalyse. Enzyme inhibitors can be competitive or non-competitive. Definition of an enzyme. Enzyme. is . protein . . catalyst. (i.e. . increase the rate of reactions. ). . NOT. changed during the reaction. 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. 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. This was mentioned earlier in 2.1, but in addition to the complexity now add to that . Enzymes:. They do all the work!. Enzymes . Proteins.

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 . 1. What are enzymes?. Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over.
