PPT-ENZYMES Lecturer: 4

Dr Shaimaa Munther ENZYMES are effective amp high specific biological catalyst that catalyze the conversion of one or more compounds substrates into one or more different compounds products. 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. Warm up. Grab warm up and complete. We will be putting this into your . journal.

Enzymes work by lowering the activation energy (the amount of energy needed to start a reaction). . 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. Human . Resources. Summer 2015. Agenda. HARP V.F.. Posting (V.F.1.).
