Instructions
You will be instructed to complete a simple demonstration –
follow the procedure below and answer the questions in the lab. It
is suggested you print this sheet and respond to the questions
here. Please upload a SINGLE file to the course site with your
answers. You should only submit page 3 & 4 of this
document.
Objectives:
3.1 Explain the processes cells use to store chemical energy and
how that energy is used to mediate chemical, transport, and
mechanical work in the cell
3.2 - Describe the location, anatomic features, and function of
each portion of the alimentary canal.
3.4 - Identify the function and regulation of enzymes secreted
by the digestive organs and glands
3.6 List the major sources and cellular uses of carbohydrates,
lipids and proteins
3.8 Explain the factors that affect an individual’s energy
requirements
Materials:
PROCEDURE
Part 1
The first thing we need to do is to prepare your gelatin
according to instructions on your brand. You should make a total of
2 cups of dissolved gelatin in water. Portion ½ cup
portions into each of your four bowls and place in refrigerator to
set.
Pause: Complete Lab Questions to Part 1
While your gelatin sets let’s talk a little bit about the
importance of the digestive system. The first concept that is
important to understand is cellular respiration. Take a
moment to review cellular respiration, then answer the questions at
the end of this lab document.
Part 2
Once your gelatin has set completely, label your four bowls “A”,
“B”, “C”, and “D”. Set “A” aside. Use a butter knife to
cut the gelatin in “B” into ½ inch sections (leave in bowl).
Sprinkle one teaspoon of meat tenderizer onto
“C”. Finally, cut “D” into ½ inch sections (leave in
bowl), then sprinkle one teaspoon of meat tenderizer onto the
surface. In summary, your four bowls of gelatin should be as
follows:
A – unmodified
B – cut
C – meat tenderizer added
D – cut, with meat tenderizer added

document.
Briefly (3 sentences) relate your observations from this
demonstration to the process of digestion. What functions of the
digestive system does this exercise demonstrate? How does that
process relate to the metabolic work within cells of the body?
(3pts)
Which organ(s) is/are responsible for the process modeled by
bowl “B”? Answer all that apply (1pt)
Which organ(s) is/are responsible for the process modeled by
bowl “C”? Answer all that apply (1pt) – please note – the main
ingredient in gelatin is collagen.
If this process were repeated with bowls of lipid, what organ(s)
would be responsible for producing the secretions that aid in
chemical digestion? Answer all that apply (1pt)
