Acids iii) Fatty acids and Glycerol 3.) a.) Each enzyme has a unique shape that fits onto the substrate. As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it doesn’t fit in (lock and key method) then the enzyme won’t be catalysed. b.) As when the enzyme is denatured it’s special shape is destroyed‚ thus destroying it’s active site meaning that the substrate wont be able to fit in‚ therefore not catalysing the enzyme. c.) As enzymes
