What is the 'active' site of enzyme

Assertion (A): Competitive inhibitors compete with natural substrate for their attachment on the active sites of enzymes. Reason (R) : In competitive inhibition, inhibitor binds to the allosteric site of the enzyme.

Identify the wrong statements (a) The substrate binds to active site of enzyme and not fitting into active site (b) The binding of substrate induces the enzyme to alter its shape (c ) Chemical bonds of substrate break down not to form now enzyme product complex (d) The enzyme releases the products of the reaction and run through catalytic cycle once again

What is active site of an enzyme?

Which forces are involved in holding the drugs to the active site of enzymes?

What is the role of competitive inhibitor during enzyme action? (a) It enhances enzyme action (b) It declines enzyme action (c) It alters the active site of the enzyme and prevents the binding of substrate (d) it inhibits breaking of chemical bond of the substrate

Arrange the steps of catalytic action of an enzyme in order and select the correct option I. The enzyme releases the products of the reaction and the enzyme is free to bind to another substrate II. The active site of enzyme is in close proximity of the substrate and breaks the chemical bonds of the substrate III. The binding of substrate induces the enzyme to alter its shape fitting more tightly around substrate. IV. The substrate binds to the active site of the enzyme

Explain with suitable diagram in how many ways a drug can bind to the active site of an enzyme thereby preventing a substrate to bind with that enzyme.

Assertion (A): Enzymes have active sites that hold substrate molecule for a chemical reaction . Reason (R) : Drugs compete with natural substrate by attaching covalently to active site of enzyme.

The temperature at which the activity of an enzyme catalyst is maximum is known as ______________

Serine, aspartic acid and phenylalanine are present at active site of an enzyme. What are the forces responsible for binding of these amino acids to active site?
