The blood concentration of blood glucose in a normal healthy human ranges between:
1. 4.5 – 5.0 mM
2. 45 – 50 mM
3. 70 – 100 nM
4. 100 – 150 mM

The correct adjective for “living state” would be:
1. An equilibrium steady state
2. An equilibrium non steady state
3. A non equilibrium steady state
4. A non equilibrium non steady state

Almost all enzymes are:

In the absence of carbonic anhydrase in the human body, the reaction between carbon dioxide and water leading to the formation of carbonic acid:
1. Will not occur
2. Will slow down considerably
3. Will get faster
4. Will remain unaltered

Which of these can have catalytic activity?

Enzymes speed up the chemical reactions by:
1. Getting used up in the reaction
2. Formation of different products
3. Converting endothermic reactions to exothermic
4. Lowering activation energy

The substrate concentration at which the enzyme catalyzed reaction achieves ½ Vmax is its ____ value.

In general, with every 10^oC rise in the temperature [in the range 0^oC to 40^oC], the rate of enzyme catalyzed reaction:
1. Becomes half
2. Gets doubled
3. Remains same
4. There is no such correlation in general

Low temperature:
1. Preserves enzyme in a temporary inactive state
2. Denatures the enzyme
3. Makes enzyme more active
4. Does not have any affect on enzyme activity

In non competitive inhibition, an increase in substrate concentration would:
1. Increase the rate of the reaction
2. Decrease the rate of the reaction
3. Not increase the rate of the reaction
4. Nullify the effect of the inhibitor
