Enzyme Catalysis

Q. Which of the following kinds of catalysis can be explained by the adsorption theory?

1. Enzyme catalysis
2. Acid-base catalysis
3. Heterogeneous catalysis
4. Homogeneous catalysis

Q. A catalyst in finely divided form is the most effective, because :

1. more active sites are formed
2. more energy get stored in the catalyst
3. none of these
4. less surface area is available

Q. If a reaction depends upon shape of catalyst, size of reactant and product molecules then the reaction is called shape-selective catalysis.

1. True
2. False

Q.

Enzymes with two sites are called [AIIMS 2002]

1. Apoenzyme

2. Holoenzyme

3. Allosteric enzyme

4. Conjugate enzyme

Q. All proteins are enzymes.

1. True
2. False

Q. All proteins are enzymes.

1. True
2. False

Q. $$\begin{gathered} \mathrm{Equilibrium}\mathrm{constant}\mathrm{of}\mathrm{reaction}2\mathrm{HI}\rightleftharpoons {\mathrm{H}}_2+{\mathrm{I}}_2\mathrm{at}\mathrm{a}\mathrm{given}\mathrm{temperature}\mathrm{is}0.01563.\mathrm{Calculate}\mathrm{the}\mathrm{equilibrium} \\ \mathrm{constants}\mathrm{for}\mathrm{the}\mathrm{following}\mathrm{reactions}. \\ \left(\mathrm{i}\right)\mathrm{HI}\rightleftharpoons \frac{1}{2}{\mathrm{H}}_2+\frac{1}{2}{\mathrm{I}}_2 \\ \left(\mathrm{ii}\right){\mathrm{H}}_2+{\mathrm{I}}_2\rightleftharpoons 2\mathrm{HI} \end{gathered}$$
