If you are absent, please watch the Amoeba Sisters video "Inside the Cell Membrane" - I showed it on the TV screen for the class. The link is here: https://youtu.be/qBCVVszQQNs?si=mjYZP-UqqsFTiRE6

The video below is required.

Phospholipids create bi-layers because of their __________________ properties

The cell membrane of a red blood cell will allow water, oxygen, carbon dioxide, and glucose to pass through. Because other substances are blocked from entering, this membrane is called

5.

Below is a diagram of a phospholipid. This macromolecule (lipid) composes all of the membranes in a cell. To understand the general structure of a phospholipid bilayer you must first be able to identify the location of the phosphate in this molecule as well as the fatty acid or lipid area.

  • A

  • B & C

  • polar

  • non-polar

  • hydrophilic

  • hydrophobic

  • Phosphate group

  • fatty acid or lipid

6.

According to the diagram above, what types of substances can easily pass through the fatty inside of a phospholipid bilayer?

7.

Explain in your own words the diagram of a phospholipid in as much detail as possible. Be sure to include:

1pt) an explanation of the structure (what is the head and what is the tail made of?)

1pt) an explanation of the polarity (which part is polar? nonpolar?)

***Remember I have to manually grade this so you will not see your score for this question until I have time to grade it.
