Which of the following statements is not correct ?

(1) Carbonic anhydrase enzyme accelerate the rate of reaction $C{O}_2$ $+$ $H_{2}C{O}_3$ $by$ ${10}^7$ times 

(2) Functional aspect of enzymes is related to the tertiary structure of proteins

(3) Enzymes are composed of only one amino acid molecule

(4) Low temperature not cause the denaturtion but inactivate the enzyme 

What level of protein organization structure explains the 3-D shape of an enzyme?

NAD and NADP are consider as

1.  Apoenzyme and cofactor respectively.

2.  Coenzyme and co-factor respectively.

3.  Both as co-enzyme.

4.  Apoenzyme and holoenzyme respectively.

How many statements are false from given
information?
(a) Ribozymes are enzyme made up of protein.

(b) In every chemical reaction transition state
energy is always greater than activation energy.

(c) Co-factors are always proteinous in nature

(d) Enzyme inhibition can not be removed.

(e) Enzyme action can be stopped at low temp.

(f) Km value (Michaelis constant) is the specific
concentration of substrate molecule.

1. 2 

2. 3

3. 4 

4. 5

Mark the Incorrect statement 

1. Co-enzymes are also organic compounds but their association with apoenzyme is only transient

2. ${V_{max}}_{}$ (maximum velocity) represent that there are no substrate molecules to bind with free enzyme molecule

3. Living state is non-equilibrium steady state to be able to perform work 

4. Enzymes eventually bring down the energy barrier making the transition of substrate to product more easy
