Digestion

• The stomach has acid that helps to break down food further and kill bacteria.
• Lipase enzymes break down fats into fatty acids and glycerol.
• Digestion begins in the mouth, where food is chewed and mixed with saliva.
• Enzymes are proteins that speed up chemical reactions inside the body.
• Things that speed up chemical reactions are called catalysts.
• Enzymes can be used over and over again so they are called reusable catalysts.
• As well as speeding up chemical reactions, enzymes also speed up the metabolism.
• The human body naturally produces enzymes, but enzymes are also manufactured in food.
• Enzymes all have a unique part to them and this part is called the active site.
• The active site will match with only one substrate and they fit together like a lock and key.
• An enzyme’s most important job is to help with digestion.
• Enzymes help to break down the food we eat into energy.
• Enzymes can be found in the intestines, pancreas, stomach and even in saliva.
• Enzymes break down proteins, carbohydrates and fats.
• Enzymes use the nutrients gained from this for growth and cell repair.
