Enzymes are very unstable compounds mostly soluble in water, dilute glycerol, NaCl and dilute alcohol. Correct option is D) The active site of an enzyme is a groove which accomodates the binding of the enzyme with the substrate and it happens by a catalytic reaction. Mechanism of Enzyme Action: Active Sites The active site of an enzyme is the region that binds substrates, co-factors and prosthetic groups and contains residue that helps to hold the substrate. All enzymes have an optimum pH value, so above or below the optimum pH, the H+ and OH- ions found in acids and alkalis can mess up the ionic bonds and hydrogen bonds, that hold the enzymes tertiary structure together this makes the active site change shape, so the enzyme is denatured. The part of the enzyme where the substrate binds is called the active site (since thats where the catalytic action happens). the active site of an enzyme is the region that binds the substrates (and cofactor if any) The interaction of the enzyme and substrate at the active site promotes the formation of the transition state.
