WebEnzyme Concentration Under normal biological conditions the substrate is present in a large excess (there is much more substrate than enzyme). As long as this condition is maintained, the addition of more enzyme results in a proportional increase in rate. pH Enzyme activity is influenced by pH with each enzyme having an optimum pH. WebBecause enzymes guide and regulate the metabolism of a cell, they tend to be carefully controlled. In this article, we’ll take a look at factors that can affect or control enzyme activity. These include pH and temperature (discussed in the active site article), as well as: Regulatory molecules. WebHydrogen peroxide is toxic and must be converted to water and oxygen by the enzyme catalase. (5.5.1) 2 H 2 O → c a t a l a s e 2 H 2 O + O 2. Hydrogen peroxide is also commonly used as a household disinfectant. It bubbles when it is applied to cuts and scrapes because catalase is present in the fluids of the broken cells. gold beach fairgrounds
