A catalyst — whether chemical or biological — acts by increasing the velocity of reactions. We will now examine the kinetics of enzymatic reactions. The velocity of an enzymatic reaction is generally followed up by measuring the quantity of substrate transformed per unit time; one can also record the quantity of the product (or one of the products) formed by [...]
In this article we will discuss about the structure of enzymes. This will also help you to draw the structure and diagram of enzymes. Enzymes are proteins, having primary, secondary, tertiary and in certain cases, even quaternary structures. Sometimes, this protein part (or apoenzyme) is not sufficient for catalytic action which then requires the presence of a co-factor. I. Polypeptide [...]
Specificity is one of the main characteristics of enzymes. It prevents the formation of by-products which happens with chemical catalysts. Specificity may be observed on the one hand in the type of reaction catalyzed by the enzyme, and on the other hand in the substrate of the reaction. Reaction-Related Specificity: A given substrate, an α-amino acid for example, can undergo [...]
