Used to make haemoglobin in red blood cells
Adds bulk to the food which helps digestion / egestion

Unsaturated
What is ingestion?
The movement of digestive food molecules into the cells of the body where they are used, becoming part of the cell
The movement of small food molecules and ions through the wall of the intestine into the blood
Breaking down of large insoluble molecules into small soluble molecules so they can pass through the wall of the intestines into the blood
Taking in of substances e.g. food and drink into mouth
What are proteins broken down into?

What is the treatment for cholera?
(a)
Where does the digestion of fats started?
Stomach
Mouth
Small intestine
Large intestine
What is the cause of cholera?
Liver unable to produce bile causing gastric acid produced in the stomach can't be neutralised leading to enzymes unable to function efficiently
Enzymes unable to function efficiently due to malfunction of the pancreas
Bacteria damage the large intestine leading to poor reabsorption of water
Vibrio cholerae produces toxin in the small intestine which causes enormous amount of water to be secreted, therefore leading to diarrhoea

What are the functions of hydrochloric acid? (Select all that apply)
Kills bacteria in the food
Gives the optimum conditions for the action of the protease enzyme pepsin
Breaks down large, insoluble food molecules into smaller, soluble food molecules for absorption
Works with pepsin during the break down of proteins into polypeptides
Which type of teeth is used for biting and cutting?
(a)
What is the cause tooth decay?
The bacteria in plaque changes sugar to acid that attacks the enamel and dentine of the tooth
Food particles contain bacteria causing obstruction of tooth
Hot food create an optimum conditions for amylase, this results amylase to also break down tooth
Acids from acidic food remain in the teeth after meal attack the enamel and dentine of the tooth
Which type of enzymes break down starch to maltose?
(a)
