The Alimentary Canal. Standard Grade Biology. Can you sort out the statements into True and False?. Carbohydrates, proteins and fats are all made up of carbon, hydrogen, nitrogen and oxygen. Fats are made up of smaller units called amino acids. Starch is a large carbohydrate molecule.
Standard Grade Biology
Carbohydrates, proteins and fats are all made up of carbon, hydrogen, nitrogen and oxygen.
Fats are made up of smaller units called amino acids
Starch is a large carbohydrate molecule
Proteins are made up of one or more glucose molecules
Starch molecules can be broken down by amylase.
Proteins are important for the growth and repair of cells
The alimentary canal (or gut) is the tube within the body through which food passes and is processed in various ways
Teeth assist the mechanical breakdown of food
Saliva is mixed with food during chewing
Saliva contains the enzyme amylase which starts the digestion of food
Saliva contains mucus that keeps the mouth moist and lubricates food for easier swallowing
The squeezing action of muscles that is used to move food along the alimentary canal
‘the breakdown of large insoluble molecules into soluble molecules’
Broken down into amino acids later by other proteases
Fats fatty acids and glycerol
