WebOne of the best things about enzymes is that they can be regulated. Regulation is important as this is how a cell controls when a reaction takes place and when it does not. Enzymes are regulated by effector molecules which are most commonly inhibitors. One way of regulating enzymes is by inhibiting them. WebEnzyme has a specific site called the active-site where substrate molecules bind to form enzyme-substrate complex. The shape of the active-site is so specific that only substrate which has a complementary shape can fit in. This is called lock and key mechanism and suggests that one enzyme can only catalyse one reaction. bearing lm30uu

WebApr 9, 2024 · Enzymes are substances present in the cell in small amounts that function to speed up or catalyze chemical reactions. On the surface of the enzyme is usually a small crevice that functions as an active site or catalytic site to which one or two specific substrates are able to bind. WebFigure 2. Simplified enzymatic reaction. The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP).

"WebVictor Heneri (1903) first proposed that the enzyme (E) combines with substrate (S) to form enzyme-substrate (ES) complex as a necessary step in enzyme catalysis. Later, Leonor Michaelis and Maude Menten (1913) expanded this concept into a general theory of enzyme action. They postulated that E first combines reversibly with S to form ES ...
