Question

Read the following four statements (A-D):-
(A) Thermal stability is an important quality of enzymes which are isolated from thermophilic organisms.
(B) Formation of Enzymes substrate complex, during enzymatic reaction, is an facultative phenomenon.
(C) Enzymes bring down the energy barrier between substrate and transition state to make the transition of substrate to product easy.
(D) The essential chemical components of many coenzymes are proteins and vitamins.
How many of the given statements are right?

• A. Four
• B. One
• C. Two
• D. Three

Answer 1

The correct option is C Two

1. Thermal stability is an important quality of enzymes which are isolated from thermophilic organisms. Eg : Taq Polymerase from Thermus Acqaticus.

2. Formation of enzyme substrate complex, during enzymatic reaction, is an obligate phenomenon.

3. Enzymes bring down the energy barrier called activation energy between substrate and transition state to make the transition of substrate to product easy.

4. The chemical components of coenzymes are non-proteinaceous and sometimes vitamin.

So, the correct option is 'Two'.
