Essay on Enzyme Activity

Enzymes are proteins that promote intracellular chemical reactions. They break down molecules called substrates. Only one matrix of each enzyme can be degraded. Enzymes are produced in somatic cells and affect the rate of almost all chemical reactions occurring in organisms. The rate of enzyme activity is influenced by temperature, pH and substrate concentration. The purpose of this experiment was to investigate the influence of enzyme activity at specific temperature changes, pH and substrate concentration. I show more content because of the heat ...

In the experiment, changes in temperature, pH, and substrate concentration were monitored to observe the influence of enzyme activity.

Enzyme activity with pH effect will be lost if pH is not at optimum pH.

3. Substrate concentration increased. If the amount of enzyme remains constant, the response to exercise will be the same.

Temperature affects enzyme activity up to the peak, which corresponds to optimal enzyme activity. When this maximum value is exceeded, the enzyme activity rapidly decreases. The optimum temperature of most mammalian enzymes is about 37 ° C. The inactivating effect at temperatures above 40 ° C is due to protein denaturation. The enzyme is regulated to suit the needs of different cells. If Km in the cell is lower than Km, please correct the activity change. An allosteric enzyme is an enzyme that is regulated by a substance that binds to a site different from the active center. The initial rate and allosteric enzyme curves are sigmoid colon, not hyperbolic. Enzyme activity also changes by covalent modification (eg phosphorylation)

Enzyme inhibitors are molecules that bind to enzymes and reduce their activity. Many drugs are enzyme inhibitors because blocking enzyme activity can kill pathogens or correct metabolic imbalances. It is also used for agricultural chemicals. Not every molecule that binds to the enzyme is an inhibitor and the enzyme activator binds to the enzyme to increase its enzymatic activity while the enzyme substrate binds and forms during the normal catalytic cycle of the enzyme It is converted into an object. Binding of the inhibitor prevents the substrate from entering the active site of the enzyme and / or prevents the enzyme from catalyzing its reaction. Inhibitor binding is reversible or irreversible. Irreversible inhibitors typically react with enzymes and are chemically altered (eg, by covalent bonds). These inhibitors modify important amino acid residues necessary for enzyme activity
