Question

a) Enzymes perform the role of _________

(b) Some enzymes require another molecule (either organic or non-organic) to be present in order for the reaction to take place. These molecules are called what?

(c) Enzymes that are able to act on a wide range of substrates, but are specific for a single type of reaction, can be explained by which model of enzyme/substrate interaction?

(d) What is the classification of enzymes that cleave bonds with water?

(e) Which group of enzymes can be said to create bonds accompanied by energy release from a hydrolysis reaction?

(f) What functional group do Kinase enzymes transfer?

(g) Which type of enzyme control is characterized by the binding of a regulator molecule to the enzyme causing a conformational change that decreases the ability of the active site to bind substrate?

(h) Does a non-competitive inhibitor bind to the active site of the target enzyme?

(i) Is noncompetitive inhibition a form of reversible or irreversible inhibition?

(j) An enzyme that is produce in an inactive form, and later undergoes modification to make it active, is known as a __________.

Answer 1

a) increasing the rate of reaction.

b) cofactor

Cofactor is an non protein chemical compound that is required for enzyme activity

c) Induced fit model

In this the active site of enzyme are more flexible and they change with substrate as substrate react with enzyme..

d)hydrolases

Hydrolases enzyme cleaves bonds by adding water  

f) phosphate group

Kinase enzyme catalyzes the transfer of phosphate group from high energy phosphate donating molecule to substrate

h) no

Non competitive inhibition occurs when inhibitor bind at non active site

I) reversible

Non competitive inhibitors are reversible.
