Question

Which of the following are not true of enzymes?

Select one:

a. The catalytic activity of enzymes is often regulated.

b. Enzymes have great catalytic power.

c. Enzymes bind substrates with high specificity.

d. Enzymes are proteins/RNA.

e. Enzymes use hydrophobic interactions exclusively in binding substrates.

Answer 1

a)some of enzymes regulated oftenly.this are called as allosteric regulation

b) enzymes have great catalytic power ..it can't disturb the equilibrium of reaction

c) enzymes have a specific sites to bind substrate.the specificity occurred by enzyme active site .one substrate can bind to two enzymes based on enzyme specificity(close fit )

d) enzymes are proteins which are composed of 100 to 1000 amino acid sequences

e) enzymes use hydrophobic interactions to bind substrate for the reaction.

Enzyme mimics hydrophobic

Answer is - c
