- Difference Between Enzymes and Hormones March 20, 2017 By Rachna C 2 Comments The enzyme is a catalyst which enhances the rate of reaction in the body whereas hormones are chemical messenger which provides the signal to the cell for performing various functions.

- Factors affecting rate of chemical reaction: concentration, pressure, temperature, nature of reactantsorientation, intesity of light, surface area, catalyst ... The enzymes lose their activity upon heating or changing the pH or adding certain chemical reagents. This is due to deformation of the configuration of active site.
- Conversely, an increased rate of metabolism decreases the intensity and duration of action as well as the drug's efficacy. Many factors may affect drug metabolism, and they are discussed in the following sections. These include age, species and strain, genetic or hereditary factors, sex, enzyme induction, and enzyme inhibition.32,483-486

Increased enzyme activity will increase? ... Factors that affect rate of reabsorption are: pH of fluid, pKA of a drug and tubular urine flow.The effect of temperature & pH on enzyme activity lesson plan template and teaching resources. PowerPoint giving the theory behind the effect of enzymes and temperature on enzyme activity.Factors Affecting Enzyme Activity * * Temperature and Enzyme Action Enzymes are most active at an optimum temperature (usually 37 °C in humans) show little activity at low temperatures lose activity at high temperatures as denaturation occurs * Enzymes are most active at optimum pH contain R groups of amino acids with proper charges at optimum ...Factors effecting Enzyme Activity Temperature • reactions occur more rapidly as temperature rises **as long as enzyme is active (heat can denature enzymes) pH • enzyme structure depends on pH [Substrate] • reactions occur more rapidly as [substrate] rises **pH affects charge of "R groups", protein structure **saturation occurs when ...
