For relatively dry plants, start with a ratio by weight of 3 parts plant material and 2 parts organic brown sugar. So they work efficiently If an enzyme is not in its optimal conditions, it doesn't work as well. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an. Model 1 – Two Digestive Enzymes. For example, if the enzyme catalase, which breaks down hydrogen peroxide,is not at a good functioning range, the body can't break down the hydrogen peroxide fast enough so there's a buildup of the toxic substance which can lead to tissue damage, or worst case death. Most enzymes have a narrow range of environmental conditions in which they will function well. substance on which the enzyme is expected to act. , how do these proteins withstand such “extreme” conditions. (Thomes, 49). Too acid or basic could alter the enzyme. Optimal C tells to liver to make L-gulonolactone oxidase and then to make vitamin C using that enzyme. An enzyme is a protein molecule. How They Work. Enzymes Natural Protection from Illness Enzymes have a great effect upon the entire immune function. What is the optimal condition for each enzyme represented by the graphs? The optimal condition is when the enzyme would work best. Change the pH and the enzyme stops working. Thus, the stomach is kept very acidic to ensure that the pepsin can work to digest protein. From equation (3) the reaction velocity, V can be expressed as: V = k2 [ES] (4) Since ES is an intermediate and hence its concentration unknown, we have to express [ES] in terms of known values. Lactase, enzyme found in the small intestine of mammals that catalyzes the breakdown of lactose (milk sugar) into the simple sugars glucose and galactose. Regardless of varying environmental conditions, the ability of thermophiles to thrive in extremely hot environments lies in extremozymes, enzymes geared to work in extremely high temperatures.
