Digestion
Question 1 – Individual Work
In the
framework of studying the importance of mechanical digestion, we realize an
experiment on in vitro digestion of lipids: sheep fat.
2 test
tubes A and B were put in a water bath of 37 degrees. We added Water and lipase
to both tubes. We added 5 g of sheep fat in 1 cube to test tube A while added 5
g of chopped sheep fat to cube B.
The mass
of sheep fat is measured at the beginning of the experiment and at the end of
the experiment. The results are shows in table 1.

Analyze
the results in document 2.
2)
Based on
the analysis, derive a conclusion.
Question 2 – Group work
An individual went to the doctor
with a problem of constipation. His doctor mentioned that he suffers from
“mal-absorption” in the small intestine.
1.
What do you think the problem of this mal-absorption
could be?
2.
Design a solution to help the individual’s digestive system’s
absorption.
