Homework Answers
Answer 18) Correct option is A
Explanation : It is the site where reactant binds the enzyme and reaction takes place.
Answer 19) Correct option is B
Explanation: Lock and key hypothesis believes active site is rigid and is complementary in shape to that of substrate.
Answer 20) Correct option is B
Explanation : First amino acid is Alanine and second is serine.
Answer 21) correct option is E
Explanation : As it bonds to site other than active site, then it is not competing with substrate.
Answer 22) correct option is D
Explanation: Both tertiary and quaternary structures are stabilized by hydrophobic interaction.
