Enzyme Factors and Conditions

Enzymes are catalysts that increase the reaction rate by reducing the activation energy required for spontaneous reactions. Most enzymes are proteins, but enzymes can be small RNA molecules or ribozymes (one enzyme on the subject is a real catalyst). Enzymes are highly specific and consist of one or more polypeptides of their native state which are usually folded into the most stable conformation. In addition, enzymes require precise conditions to catalyze different kinds of reactions (Subject 2-specific, Tymoczko, J .;

Many other factors also affect the activity of the enzyme. Most enzymes function only under optimal environmental conditions. If pH or temperature deviates too far from these conditions, enzymatic reactions are significantly slower or do not work at all. You may have noticed an extra step in the process

Enzyme kinetics is a study of enzymatic catalysis chemistry. In the enzyme kinetics, the reaction rate was measured and the effect of changing the reaction conditions was investigated. Studying the kinetics of enzymes in this manner reveals the catalytic mechanism of the enzyme, its role in metabolism, how its activity is controlled, and how drugs or agonists inhibit enzymes . These mechanisms can be divided into single substrate mechanisms and multiple substrate mechanisms. Kinetic studies of enzymes that bind only to one substrate (eg, triosephosphate isomerase) are designed to measure the affinity and conversion rate of the enzyme to bind to the substrate. Other examples of enzymes are phosphofructokinase and hexokinase, both of which are important for cell respiration (glycolysis).

Enzymes are very specific in environmental factors affecting reaction rate. This enzyme is suitable only for matrices suitable for the active site and not suitable for other genes (Campbell 2008). This enzyme binds to a substrate called amino acid active site (Enzyme 2007). The substrate enters the active site, allowing the enzyme to change shape, allowing the active site to envelop the substrate and more readily catalyze the reaction. In addition, the more substrate molecules available, the more frequent they enter the active site (Campbell 2008). Because the enzyme supports the most active form of the enzyme molecule, the enzyme works more effectively under optimum conditions (enzyme concentration, substrate concentration, temperature, pH etc). However, when conditions are changed extremely, enzymes degenerate and the effect decreases (Campbell 2008).
