Given below are the four schematic that describe the dependence of the rate of an enzymatic reaction on temperature which of the following combinations is true for thermophilic and psychrophilic organisms ?

Options

A. P and P
B. P and S
C. P and R
D. R and R

Answer

d

Explanation

Being mostly proteinaceous enzymes are liable to temperature. Themosphiles are living at very high temperature while psyrophiles live in the range of `-20^(@)C "to" + 10^(@)C` . In either case rising temperature will first raise the rate of reaction but if temperature is still raised continuosly enzyme get denatured hence reaction rate decreases.
