Plasms Membrane
I feel you did a great job on your assignment for this week explaining the properties of the cell membrane with the correct terms integral proteins, channel proteins and bilipid construction. Your last paragraph was very detailed with great information about the cell membrane, you stated “ The cell membrane is very thin and fragile, and it contains two different types of proteins. “Integral proteins are part of the membrane structure and cannot be removed without damaging or destroying the membrane. Peripheral proteins are bound to the inner or outer surface of the membrane and are easily separated from it” (Martini, 2009, p.71). Channel proteins are described perfectly by its name. It acts as a channel to the cell membrane allowing certain nutrients to move throughout or completely through the membrane”. My first question is what would happen to the cell if the cell membrane (plasma membrane), fails to work? Why? Are there any disorders that can be affected by the cells or plasma membrane? Explain? Some cool facts that I have learned about cells are you need a scanning electron or transmission electron microscope to view a cell because cells range in size from 1 to 100 micrometers. Did you know that cells contain genetic material like DNA, nucleic acid and cytoplasm? Our body’s cells contain 23 pairs of chromosomes! Again, great job on your assignment for this week’s lesson of the functions of the cell membrane (plasma membrane), with the correct terms integral proteins, channel proteins and bilipid construction. Keep up the hard work and thank you for your great
