Reading Quiz!
I will stamp your notes!
Then we will take our quiz
When done quietly work on the warm up and or read
through the diabetes article again!
Warm Up: Silent 9/15
1. Define homeostasis
2. Define set-point
3. Explain a negative feedback system in your
body
Task: Make a concept map on diabetes and
how blood sugar is regulated in your body
• Use our class concept map as a starting point
• You will read the article “How Diabetes Works”
independently
• Develop a list of key concepts and words that should be
included on your map in your Notes Section
• As a group decide on at least 12 key words to include on
your map, write them on post it notes.
• Draw arrows with connecting words between the post its to
complete your concept map

Make a candy-corn membrane!
Hydrophobic - white tip
Hydrophilic - yellow head
Pretend ALL your candy
corns are sitting in water!
Arrange them so that each
side is "happy."

Cell Membrane Assignment pages 77-78 of text
What are the two organic molecules that make up all
membranes?
Draw and label a single phospholipid molecule. Label the polar
head and the nonpolar tail of the phospholipid.
What do the terms HYDROPHOBIC and HYDROPHILLIC mean
and which parts of the phospholipid do these terms refer to?
Why is the membrane referred to as a PHOSPHOLIPID
BILAYER?
What is the difference between an integral protein and a
peripheral protein in terms of location?
What roles do these proteins serve for the membrane?
What do the terms “FLUID” and “MOSAIC” refer to in terms of
the membrane?
