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
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
According to the diagram above, what types of substances can easily pass through the fatty inside of a phospholipid bilayer?
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.
Make the correct function to each item below.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
carbohydrates (or sugar groups) | arrow_right_alt | transports some substances through the membrane |
integral proteins | arrow_right_alt | makes sure the phospholipids don't move too far apart or get too close together |
cholesterols | arrow_right_alt | important for cell recognition so your immune system cells can identify foreign cells like bacteria |
Put the words below into the appropriate classification.
