Parts of the Cell!!!
Cell Membrane
How does it work?
The cell membrane is the outer boundary of the cell. This outer boundary is very thing being only about 6-10 mm thick. This boundary contains lipids, proteins, and carbohydrates. The main two different proteins are called either integral or peripheral proteins that are bound to the interior or outer surface of the membrane. The integral flat protein floating on either side of the membrane. Whereas the peripheral proteins are the tall proteins coming straight through the membrane. Although both of the proteins can be easily taken out of the membrane. Why is it important? The cell membrane is important because of all of its functions that it preforms. The cell membrane has physical isolation that separates the inside of the cell from the outside. This could be explained as a wall around a house. Another function is that it regulates the exchange with the environment. The membrane does this by allowing nutrients to get in, but by eliminating waste from the cellular process. It also responds to different indicators outside of the cell. The membrane is the structure of the cell, keeping it together, and protecting the cell itself. Finally, the most amazing of the functions that a cell can have is the membrane can bond with other membranes. Example: |
Cytosol
How does it work?
A part of the cytoplasm, the cytosol contains dissolved nutrients, ions, soluble, and insoluble proteins and waste products. Why is it important? The cytosol is important because of what it holds and how much of it does hold. The cytosol contains a high concentration of suspended proteins that help regulate the metabolic operation associated with the various organelles. The cutosol usually contains small quantities of carbohydrates, and small reserves of amino acids and lipids. The carbohydrates become broken down to provide energy, and the amino acids are used to manufacture proteins. Also, the lipids are used as a source of energy when carbohydrates are unavailable. |
