Questions
Which of the following is correct with reference to enzymes?
a
Enzymes work efficiently at high temperatures and high pressures.
b
Enzymes through their allosteric site, catalyse reactions at a higher rates.
c
An active site of an enzyme is a crevice or pocket into which the substrate is bound.
d
Thermal stability is an important quality of enzymes isolated from halophilic organisms.
detailed solution
Correct option is C
In the tertiary structure of proteins it is noticed that the backbone of the protein chain folds upon itself, the chain criss-crosses itself and many crevices or pockets are made. One such pocket is the ‘active site’. An active site of an enzyme is a crevice or pocket into which the substrate is bound. Thus enzymes, through their active site, catalyse biochemical reactions at a higher rates.Talk to our academic expert!
