Enzymes are complex proteins, and each enzyme has a specific structure designed to work with a particular reaction. A substrate is a specific reactant that an enzyme acts on. Another way to affect the enzyme is by lowering the pH of the solution. but if its too high it will denature the protein rendering What Effects of Concentrations of a Substrate on Enzyme Lab Answers. Enzymes break down molecules called substrates. The equation for this reaction follows: Background: Enzymes act as catalysts to help chemical reactions occur. In general, each enzyme is highly specific for a particular substrate, in that each usually catalyzes only a single chemical reaction. It is important to measure the initial velocity, or vo. Students use an indirect measure of enzyme function (glucose test strips) to explore how temperature and pH affect the enzyme lactase. The first thing to be mentioned is that enzymes are biological molecules made up of a complex protein that catalyzes specific chemical change in living organisms. Inorganic 3. Catalase is 9.

It helps accelerate reactions by lowering the activation energy, which is needed for reactions in cells to progress at a higher rate. The effect on concentration, temperature, and pH on catalyst Enzyme activity . For most human enzymes, an optimal pH is 7. A substrate is a molecule that temporarily binds with the enzyme at an area on the enzyme called the active site. Enzymes have an optimum pH where they function the best. For the first experiment, Observing the Enzyme Reaction, it was hypothesized that the enzyme reaction would only occur in the second test tube due to the fact that it was the only tube to contain both the enzyme and substrate.
