Digestion + enzymens Flashcards
(17 cards)
amylase
breaks down starch into into maltose
maltase
breaks down maltose into glucose
Protease
breaks down proteins into amino acids
Lipase
breaks down lipids into fatty acids + glycerol
Where is Bile stored, produces and what does it do
produced: liver
stored: gall bladder
do: neutralises stomach acid and breaks down lipids into small pieces
peristalsis
waves of muscle contractions which move food down the oesophagus
How many enzymes for each substrate
1
how does temp / PH affect enzyme activity
-rates of reaction increase as temp increases
-increased KE
-up until optimum temp
-rate decreases as active site changes shape
-substrate can no longer bind
-enzyme denatures
what is absorption
movement of digested food molecules from the digestive system into the blood (glucose and amino acids) and lymph (fatty acids ect)
what is assimilation
process by which living organisms convert food into vitamins and minerals and other chemicals needed for body to function
what is egestion
process of passing out the remains of the food that has not been digested as faeces through the anus
what is an enzyme
biological catalyst that increases the rate of reaction without being used up
what enzyme in mouth
amylase
what does pancreas produce
carbohydrase
protease
lipase
insulin
first section of small intestine
duodenum
second part of small intestine
ileum
where is bile released to
duodenum
