- universal indicator
we test foods for glucose using
- benedict's solution
- biuret solution
- universal indicator
- iodine
we test foods for protein using

amylase
- is an enzyme that breaks starch down into glucose
- is an enzyme that breaks down fats
- carries oxygen in your bloodstream
- is an enzyme that breaks down proteins
During digestion, proteins
- are broken down into amino acids
- are broken down into glucose
- are not broken down
- are broken down into fatty acids
During digestion, fats
- are broken down into fatty acids
- are broken down into amino acids
- are broken down into glucose
- are not broken down
We need to digest foods
- to break them down so that they can pass into your bloodstream
- to break them down so that they can pass along your gut
- to get rid of toxic substances
- in order to get rid of waste
An enzyme
- usually works best at body temperature
- works best when they're heated strongly
- can be used on a wide variety of molecules
- is an essential part of our diet
The oesophagus
- is another name for the gullet
- is where acid is added to the food to break it down
- is where nutrients are absorbed into the bloodstream
- digests fats
the stomach
- is where acid is added to the food
- is another name for the gullet
- digests fats
- recovers water from the food
the small intestine
- is where most nutrients pass into the bloodstream
- is where acid is added to the food
- is where waste is stored
- recovers water from the food
the large intestine
- recovers water from the food
- is where acid is added to the food
- digests fats
- is where most nutrients pass into the bloodstream
the colon is
- the large intestine
- the small intestine
- where acid is added to the food
- made of two semi-colons
the ileum is
- the small intestine
- is where acid is added to the food
- the large intestine
- where waste is stored
the stomach is
- where acid is added to the food
- where most nutrients pass into the bloodstream
- where waste is stored
- where water is recovered from the food
The digestive system:
- mouth, gullet, stomach, small intestine, large intestine, rectum, anus
- mouth, gullet, stomach, large intestine, small intestine, rectum, anus
- mouth, stomach, gullet, large intestine, small intestine, rectum, anus
- mouth, gullet, small intestine, stomach, large intestine, rectum, anus
Digestion begins
- in the mouth, with enzymes in saliva
- in the stomach, with acid
- in the liver
- in the pancreas
Visking tubing
- has tiny holes in the wall that only small molecules can pass through
- is waterproof
- is part of your gut
- will allow starch molecules to pass through the walls
fibre
- gives bulk to the food
- contains energy
- is needed for growth
- is needed for storing energy
we know that there is glucose in a food if it
- makes warm Benedict's solution turn orange
- makes warm Benedict's solution turn blue
- makes iodine turn blue-black
- makes iodine turn brown
