What are enzymes

Answer 16

Enzymes are biological or catalysis they increase the speed of chemical reactions they breakdown large food molecules down into smaller ones

Question 17

Why do we have to breathe

Answer 17

Because all of the cells in our bodies need energy to stay alive we get energy out of our food in respiration

Question 18

What is physical digestion

Enzymes are chemicals that break down food into very small molecules that can be absorbed into our blood

Question 20

Mouth

Saliva glands produce saliva the teeth chop the food into smaller pieces saliva contains a carbohydrates enzyme that digests starch

Question 21

Gullet

Answer 21

Muscular tube that transports food to the stomach muscles contract to push the food down the tube this is called peristalsis

Question 22

Stomach

Answer 22

Produces a protease enzymes therefore protein foods Are digested here produces hydrochloric acid which kills bacteria and provides the correct pH for the enzyme

Question 23

Small intestine

Answer 23

Large intestine

Answer 24

Water is reabsorbed and the faeces are formed
