This PowerPoint helps students to consider the concept of infinity.
enzyme regulation
1. Enzymes Pt 3: Regulation of enzyme activity Relicardo M. Coloso, Ph. D. College of Medicine Central Philippine University
2. Regulate – to control or direct according to a rule, principle or law Enzyme regulation- is the control of the rate of a reaction catalyzed by an enzyme by some effector (e.g., inhibitors or activators) or by alteration of some condition (e.g., pH or ionic strength).
3. Five ways by which enzyme activity in the cell can be changed: 1. Enzyme production – synthesis or degradation 2. Compartmentation – different metabolic pathways occur in different cell compartments 3. Activation and inhibition – by activators or inhibitors, for example feed back inhibition by one of products of the reaction 4. Post-translational modification – for example by phosphorylation, methylation, glycosylation 5. Localization to a different environment – from a reducing (cytoplasm) to an oxidizing (periplasm) environment, of high pH to a low pH, or low salinity to high salinity, high to low energy charge
