Question

Describe an investigation into the effect of bile on fat digestion. You are given some cloudy fat suspension which turns clear when all the fat in it has been digested. You are also given some bile and lipase solution. Be sure to make your investigation valid and reliable.


I would be extremely grateful to anyone who can explain to me or shed light on this- even if it's the slightest information! Cheers!

Answer 1

so we know that bile breaks up fat molecules to speed up the process of fat digestion

Answer 2

Yes.

Answer 3

Now we have some suspension that has fat in it so we prepare two tubes with this suspension. In one we also add bile and measure the time with a stopwatch until the suspension turns clear -

In the other we do the same but adding lipase
then we compare the times it takes for bile and lipase to clear the test tube
as bile speeds up the process of digestion. We would expect the time for the first tube to be way faster than the time for the tube with lipase... and there we have our experiment.
