Answer 5

salivary glands, pancreas, small intestine

Question 6

Answer 6

protease

Question 7

what does protease break down

Answer 7

proteins

Question 8

what is protein converted into

Answer 8

amino acids

Question 9

which 3 places is protease made in

Answer 9

stomach, pancreas, small intestine

Question 10

what is an example of lipases

Answer 10

lipase

Question 11

what does lipase break down

Answer 11

lipids

Question 12

what is lipids converted into

glycerol and fatty acids

Question 13

which 2 places is lipase made in

Answer 13

pancreas, small intestine

Question 14

what is the job of bile

Answer 14

neutralises the stomach acid and breaks down fats

Question 15

where is bile produced and stored

Answer 15

produced in the liver, stored in gall bladder

Question 16

Answer 16

the hydrochloric acid in the stomach makes the pH too acidic for enzymes to work properly. Bile is an alkaline, it neutralises the acid

Question 17

how does bile emulsify fat

Answer 17

it breaks it down into small droplets, this gives it a much bigger surface area for the lipase to work on, which makes digestion faster

Question 18

what are products of digestion used for

Answer 18

build new carbohydrates, lipids and proteins. some glucose is used in respiration
