Enzyme Specificity And Inhibitors In Biochemistry

Enzyme Specificity And Inhibitors In Biochemistry

Describe the following aspects of enzymes:

1. Specificity
2. Four factors influencing enzyme activity
3. Competitive enzyme inhibition.

Answer:

Enzymes Specificity:

• Enzymes are highly specific in their actions

Enzymes Types of specifically:

Factors influencing enzyme activity:

Competitive enzyme inhibition:

• The inhibitor which is structurally similar to the substrate competes with the substrate for the binding site.
• This diverts the enzyme to form an enzyme inhibitor complex instead of an enzyme-substrate complex.
• This complex does not produce any products and remains stable.
• It results in the prevention of further enzymatic activity.
• This is known as competitive inhibition.
• It can be reversed by adding an excess of the substrate which will dislodge the inhibitor.
• The action of drugs depends on the inhibitor present
