Identify the given nitrogenous base:
 

1.	Adenine	2.	Guanine
3.	Thymine	4.	Cytosine

Almost all enzymes are:

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

The non protein constituent present in many enzymes is called:

Haem in hemoglobin:
1. is loosely bound
2. is the co-enzyme
3. is the prosthetic group
4. has no influence on activity of Hb

What is the co-factor for the proteolytic enzyme, carboxypeptidase?

Most of the coenzymes contain:

Most common element present in human body is:

Which of the following is not an aromatic amino acid?
