Site 2: Small intestine
Site 3: Large intestine
Site 4: Anus ;)

Question bi: Pepsin, Lipase, Enterokinase, Amylase, Sucrase, Lactase
Question bii: It could be due to the bile secreted by the liver into the digesting food, when the food enters the small intestine, it increases the pH of the small intestine.

Question ci: Because the food enters the stomach, the protease  will digest the food down into simpler substances, like amino acids. This causes the increase of amino acids in Site 2.

Question cii: All the fats has been digested by the lipase and absorbed into the bloodstream at the small intestine.]]> 2016-07-26 02:28:06 UTC https://padlet.com/cheah_qinling/tables_DBQ/wish/116969558 https://padlet.com/cheah_qinling/tables_DBQ/wish/116970348 question 1: 
a) carbohydrates -- amylase -- maltose-- maltase --glucose

proteins -- protease-- polypeptides --pepsin-- amino acids

b) Fats is digested by lipase into fatty acids and glycerol.This is absorded into the lymphatic vessel and then transported to other parts of the body.Excessive intake of fats can caused clogged arteries and coronary heart disease.

c)The cellulose content in the faeces will be higher than the starch content because our body is unable to absorb and digest cellulose and thus almost all cellulose are passed out in our faeces while starch is absorbed and digested by enzymes like amylase and transported to other parts of our body and used to provide energy.]]> 2016-07-26 02:32:20 UTC https://padlet.com/cheah_qinling/tables_DBQ/wish/116970348 https://padlet.com/cheah_qinling/tables_DBQ/wish/116970600 1a the suction force removes the air from the water which leave co2 in the water. The leaves use co2 to produce oxygen which is lighter, hence, the leaves sink.

starch ----(amylase)---> maltose ----(maltase)---> glucose

fats ----(lipase)---> glycerol+ fatty acid 

1(b) 
how fats can be assimilated:
- fats can be converted into glucose to be use as energy
- fats can be stored and use to insulate heat and keep the body warm

how fats can be harmful:
- excessive fats can clogged blood vessels which caused lumens to become smaller and increases pressure as the heart needs to pump blood faster
causing coronary heart disease and high blood pressure.
- excessive fats stored can also cause obesity 

1(c) starch can be absorbed during digestion whereas cellulose cannot be absorbed by the human body hence it will excrete all the cellulose in our faeces, therefore no difference in intake and loss for cellulose]]> 2016-07-26 02:48:13 UTC https://padlet.com/cheah_qinling/tables_DBQ/wish/116972282 https://padlet.com/cheah_qinling/tables_DBQ/wish/116972309 a1) stomach

cii) all fats are broken down in the small intestine by bile and lipase into glycerol and fatty acid
