Factors affecting enzyme reactions

Revision from last lesson What is a catalyst? What is the name for biological catalysts? Where are enzymes found? Why are enzymes necessary for life? Name the substrate and product in the following reaction…… starch maltose amylase

Have you finished the tasks from last lesson? You should have A paragraph describing the action of amylase A diagram illustrating lock and key theory A list of key words and definitions

Denaturing High temperatures OR Change from normal pH range Damage is irreversible Enzyme will no longer work Enzyme said to have denatured At low temperatures enzyme action is very slow as enzyme is fairly inactive (but not denatured) Change an enzyme’s 3-dimensional structure
