Cell Membrane

Inside the Cell Membrane Video In case you want to watch this again (or maybe for the first time)The "good stuff" begins at 3:27. Cell Membrane Video Lecture To be used to take the Cell Membrane notes. Label the parts of the Cell Membrane:Please use all lowercase. Word Bank:cholesterol, integral protein, phospholipid molecule, peripheral protein integral protein peripheral protein phospholipid molecule cholesterol Label the Phospholipid Molecule:Be sure to use lowercase letters. Word Bank:dislikes, head, likes, philic, phobic, tail head philic likes tail phobic dislikes Complete the paragraph below:Be sure to read over your completed statements before submitting. The cell membrane is also known as the phospholipid bilayer. This means that the cell membrane is actually comprised of two layers. One layer is positioned right side up and the other is positioned upside down due to polarity. The phosphate heads are located on the "outside" of the cell membrane because it is polar which means it is attracted to water. The fatty acid tails are located on the "inside" of the cell membrane because they are non-polar and not attracted to water. Cell Membrane Puzzle To mark a word click its first letter then click its last. HYDROPHILIC CHOLESTEROL HYDROPHOBIC RECOGNITION FLUIDITY PASSAGE BILAYER MOSAIC Proteins in the Cell Membrane:Complete the statements below by filling in the blanks. Please read over your completed statements before submitting. The cell membrane controls what comes into and out of a cell. The main actor in this important function is the protein. Some proteins are integral which means that they are embedded in the cell membrane from one side to the other. The role of these proteins, which may be called 'channel" proteins is to aid the movement of certain substances into and out of the cell.Some proteins are only on the outside part of the cell membrane. These proteins may be connected to carbohydrates which makes them a glycoprotein. These peripheral proteins are responsible for the cells ability to recognize self from non-self. This is how our immune system knows when to prepare to defend us. Cholesterol of the Cell Membrane:Complete the statements below by filling in the blanks. Please read over your completed statements before submitting. Cholesterol is a structural part of the cell membrane. The cholesterol can be found located between the phospholipid molecules in a layer. The cholesterol's main role is to regulate the fluidity of the cell membrane.
