1.	Which of these statements is true regarding competitive inhibitors?(a) It inhibits the activity of substrate(b) Malonate increases succinic dehydrogenase activity(c) They are structurally different from the substrate(d) They are used in the control of bacterial pathogensThis question was posed to me in an international level competition.My doubt is from Biomolecules in chapter Biomolecules of Biology – Class 11
Answer» The correct CHOICE is (d) They are used in the control of bacterial pathogens To elaborate: Competitive inhibitors inhibits the ACTIVITY of ENZYMES. They are structurally SIMILAR to the substrate. MALONATE is a competitive inhibitor for succinic dehydrogenase. They are used to control pathogens.
