1.	Identify the correct statement about enzymes.(a) Enzymes increase the activation energy of a reaction(b) Enzymes need to be used in excess compared to the reagent to catalyse the reaction(c) Enzymes work only at their optimum temperature and pH(d) The activity of enzymes cannot be affected by other compoundsI got this question in an interview.My doubt is from Biomolecules in division Biomolecules of Chemistry – Class 12
Answer» CORRECT option is (c) Enzymes work only at their optimum temperature and pH The explanation is: Enzymes decrease the activation ENERGY of a reaction. EXTREMELY SMALL quantities of enzymes can increase the rate of reaction by thousands. Enzyme action can be inhibited by compounds known as enzyme inhibitors.
