Food and Digestion Flashcards
What are the 7 nutrients?
Protein, Carbohydrates, Minerals,Fat/Lipids, Fibre, Water and Vitamins.
Sadly, Pork pie and dumplings are not classed as nutrients :(
What is a balanced diet?
When you eat the right types of food in the right amount to get the nutrients needed.
What is definition of Mastication?
To crush down food with your teeth.
Where does the food you eat become part of your body
The teeny weeny small intestine!
The folds in the wall of the small intestine make the surface area …………. times bigger.
500!!
What does the villi have/do
nufin bruv
Thin walls, large surface area, can produce mucus for lubrication, and can change the concentration of glucose from high to low, all to help the small molecules move FASTER
Which parts of your body do mechanical digestion?
MOUTH and STOMACH are like MACHINES bruv
Here is a fact for ya bruv
dont tell anyone!
The enzymes chemically react with the nutrients to break bonds and turn the nutrients into smaller molecules that can fit through the lining of the teeny weeny small intestine
What breaks up the starch molecule and what does it make?
Carbohydrase, which turns it into small glucose molecules for energy
What breaks up the Protein molecule and what does it make?
Protease, which makes small amino acids for building cell components
What breaks up the fat molecule and what does it make?
Lipase, which makes fatty, farty acid and glycerol for building cell membranes and to give you ENERGY
Which enzymes break down fibre?
None! Trick question! Fooled you!!
None of our enzymes can break down fibre so we can’t get any nutrients. Fibre is used to shove out the poo so you don’t get constipated
What is amylase?
A type of carbohydrase found in saliva, which breaks down starch into sugar.
What is the best temperature for amylase?
37 degrees and neutral pH
The temperature of your mouth!
Some INFO for ya bruv
The enzymes fit with the substrates go together like a lock and key
Amylase goes with starch, but doesn’t fit with protein, like a key in the wrong lock
It’s really annoying when that happens innit bruv!
