    Cell Membranes Tutorial
    This exercise introduces the dynamic complexes of proteins, carbohydrates, and lipids that comprise cell membranes. You should learn that membranes are fluid, with components that move, change, and perform vital physiological roles as they allow cells to communicate with each other and their environment. We also show that membranes also are important for regulating ion and molecular traffic flow between cells,and that defects in membrane components lead to many significant diseases.

    Cell Signaling Problem Set
    Living organisms constantly receive and interpret signals from their environment. Signals can come in the form of light, heat, water, odors, touch, or sound. Cells of multi-cellular organisms also receive signals from other cells, including signals for cell division and differentiation. The majority of cells in our bodies must constantly receive signals that keep them alive and functioning. All organisms also have signaling systems that warn of the presence of pathogens, leading to a protective response.


    The key concept is that the many signaling systems of biology have very similar or related steps. The same signaling system can lead to very different responses in different cells or different organisms. Studies of the mechanisms of cell signaling are leading to new understanding of many diseases, and to new strategies for therapy.
