Does glycerol, fatty acids, amino acids and glucose all respire and used for energy?
No, amino acids are nused as raw materials to make new proteins for growth
4 of 25
Mouth
Starts the digestion of starch (main carbohydrate)
5 of 25
Oesophagus
Food is pushed down into stomach. No digestion
6 of 25
Liver
Produces bile, which helps digestion of fat
7 of 25
Gall bladder
stores bile, the releases it into stomach.
8 of 25
Stomach
starts digestion of proteins
9 of 25
Pancreas
produces lipase and carbohydrase
10 of 25
Rectum
stores faeces before egestion
11 of 25
Anus
egests faeces
12 of 25
Large intestine
reabsorbs water that has been added in digestive juices
13 of 25
small intestine
completes digestion of proteins which are broken down into amino acids by the enzyme protease. Completes digestion of carbohydrates, which are broken down into glucose by the enzyme pancreatic carbohydrase. Digests fats which are broken down into

Where does digestion take place
mouth, stomach and small intestine

Where does absorbtion occur?
small intestine (food) and large intestine (water)

What's villi
small finger-like projections which greatly increase the surface area of the small intestine.

Test for protein
If protein is present, it will go a purple colour, this is called the Biuret test or the Biuret solution (if both sodium hydroxide and copper sulfate are combined into one solution.

Test for starch
blue-black if starch is present
24 of 25
Test for glucose
brick red and is called Benedict's test.
