definition of an organ
The digestive system
label the parts and describe the functions
where does digestion occur in the digestive system (three organs)
explain
how are villi adapted to their function?
many microvilli
villus walls are one cell thick
good blood supply
cells have many mitochondria
enzymes
what is an enzyme and what do they do?
draw and label a simple model of the 'lock and key' hypothesis
Required practical activity 4:
investigate the effect of pH on the rate of reaction of amylase enzyme
method-identify the independent, dependent and control variables
draw a graph
and explain
how temperature effects enzyme activity
draw a graph
and explain
how pH effects enzyme activity
what is meant by 'rate of reaction'?
how do you calculate the rate of reaction
over a period time
?
how do you calculate the rate of reaction
at a specific time
?
digestion
Required practical activity 3:
use qualitative reagents to test for a range of carbohydrates, lipids and proteins
test for starch
test for proteins
test for simple sugars
test for lipids
why is digestion important?
what are the following broken down into
and
why do we need them in our diet?
carbohydrates
proteins
lipids
digestive enzymes
amylase
sites of production
what does it break down?
protease
sites of production
what does it break down?
lipase
site of production
what does it break down?
bile
where is made and where is it stored?
why is it needed in digestion?
