INTRODUCTION Enzymes are biological catalysts that speed up chemical reactions‚ without being used up or changed. Catalase is a globular protein molecule that is found in all living cells. A globular protein is a protein with its molecules curled up into a ’ball’ shape. All enzymes have an active site. This is where another molecule(s) can bind with the enzyme. This molecule is known as the substrate. When the substrate binds with the enzyme‚ a product is produced. Enzymes are specific to their
