Question

Match the following and choose the correct option.

$\begin{array}{cccc}\text{(a)}& \text{Inhibitor}& \left(i\right)& \text{Most abundant protein in animal world}\\ \text{(b)}& \text{Abrin}& \text{(ii)}& \text{Homopolysaccharide present in exoskeleton of insects}\\ \text{(c)}& \text{Collagen}& \text{(iii)}& \text{A plant toxin, considered as secondary metabolite}\\ \text{(d)}& \text{Chitin}& \text{(iv)}& \text{A chemical which shuts off enzyme activity}\end{array}$

• A. (a) - (iii), (b) - (i), (c) - (iv), (d) - (ii)
• B. (a) - (iv), (b) - (iii), (c) - (ii), (d) - (i)
• C. (a) - (iv), (b) - (iii), (c) - (i), (d) - (ii)
• D. (a) - (ii), (b) - (iv), (c) - (iii), (d) - (i)

Answer 1

The correct option is C (a) - (iv), (b) - (iii), (c) - (i), (d) - (ii)

Abrin is toxin obtained from Abrus plant. When the binding of the chemical shuts off enzyme activity, the process is called inhibition and the chemical is called an inhibitor. RuBisCO is most abundant protein in whole of the biosphere. Collagen is the most abundant protein in animal world.
