Day 6 -- Normal Routine

With a lack of experiments to do and an abundance of written works to be started, we didn't do anything noteworthy today.

The class started by diagramming the cell membrane, explaining the parts of it, and learning the functions. There were a number of facts thrown at us all at once, but the main gist was as follows:

• The Cell Membrane is a semi-permeable membrane that all living organisms contain (except for viruses). 
• The structure consists of a Phospholipid Bilayer, or layers of hydrophilic phosphates with attached hydrophobic lipids, as the "wall."
• Proteins are considered "gatekeepers" and do many tasks, including transport, signal transduction, cell-to-cell recognition, and operation of enzymatic activity.
• Diffusion is carried out through carrier proteins (change in shape to allow particles through) and channel proteins (a gateway for particles that requires ATP).
• Osmosis is carried out because polar molecules (as Mr. Quick put it) "love" proteins. (See picture)

The class is bound to have another large quiz or test, it's just a matter of time. Hopefully, this won't be on it.
