Factors Affecting Enzymatic Activity

In the previous post, we have discussed the Properties of Enzymes. In the present post, we will see what all are the factors that affect the catalytic activity of an enzyme in the living system.

Factors Affecting Enzymatic Activity

Ø  The catalytic activities of enzymes are affected by multiple factors. They can be summarized as:

effect of pH on enzymatic activity(1).   Temperature

(2).   Water

(3).   Hydrogen ion Concentration (pH)

(4).   Concentration of Substrate

(5).   Concentration of Enzyme

(6).   Inhibitors

(7).   Accumulation of End-products

(8).   Effect of activators

(9).   Effect of light and radiation

(1). Temperature

Ø  The enzymatic activity will be optimum at normal temperature.

Properties of Enzymes
(Catalytic Property, Specificity, Reversibility and Sensitivity to Heat and pH)

Enzymes are biological catalysis. They are specialized proteins (except ribozymes) capable of catalyzing specific reactions in the cells. In the previous post, we have discussed the Structure and Functions of Enzymes. In the present post, we will discuss the Properties of Enzymes.

What are the Properties of Enzymes?

@. The properties of an enzyme can be summarized as:

(1). Catalytic Property

(2). Specificity

(3). Reversibility

(4). Sensitiveness to Heat and Temperature

(5). Specific to Hydrogen Ion Concentration (pH)

What are Enzymes?

There are thousands of chemical reactions in a living system. The chemical reactions in the cell are catalyzed by the biological catalysts called enzymes. Almost all enzymes are highly specialized proteins. (Exception: Ribozymes –Ribozymes are RNA with catalytic activity). The current post we will discuss the Characteristics of Enzymes. We will also discuss the features of a Catalyst and the concept of Activation Energy of a reaction.

What are catalysts?

Ø  The catalyst is substances that accelerate the rate of a chemical reaction.

Ø  The catalyst is not consumed or transformed by the reaction.

Ø  It will not change the equilibrium constant of the reaction.

Ø  Catalysts only change the rate to approach equilibrium constant.

Ø  Catalysts are not required in stoichiometric quantities.
