Enzymes and digestion

Question 1

what does the digestive system do to break big molecules such as starch, proteins and fats

Answer 1

break these big molecules into smaller ones such as sugars, amino acids, glycerol and fatty acids.

Question 2

what does carbohydrates/starch turn into

Answer 2

starch goes to amylase which is an enzyme which then turn to simple sugars

Question 3

what does proteins turn into

Answer 3

proteins turn into protease which is an enzyme which then turn into amino acids

Question 4

what do lipids/fats turn into

Answer 4

lipid goes to lipase which is an enzyme then turns into glycerol and fatty acids

Question 5

where is amylase made

Answer 5

1) the salivary gland
2) the pancreas
3) small intestine

Question 6

where are proteases made

Answer 6

1) the stomach (its called pepsin there)
2) the pancreas
3) the small intestine

Question 7

where are lipases made

Answer 7

1) the pancreas
2) small intestine

Question 8

where is bile produced and stored

Answer 8

produced in the liver and is stored in the gall bladder before it is released into the small intestine

Question 9

why is bile the best working area for enzymes

Answer 9

bile is alkaline - it neutralises the acid and makes conditions alkaline.
the enzymes in the small intestine work best in these alkaline conditions
