Enzymes

• To catalyse a reaction, the reacting chemical (substrate) must bind to the enzyme's active site.
• Enzymes are also known as biological catalysts.
• Once the optimum temperature has been reached, the activity decreases.
• The sites of action for amylase are the small intestine and the mouth.
• Lipase breaks lipids down into fatty acids and glycerol
• Carbohydrases convert carbs i.e. starch into simple sugars
• Amylase is an example of a carbohydrate that breaks down starch
• Amylase is made in the salivary glands, pancreas and small intestine
• Proteases convert proteins into amino acids
• Proteases are made in the stomach (as pepsin), the pancreas and the small intestine
• Lipases convert lipids into fatty acids and glycerol
• Lipases are made in the pancreas and the small intestine
