These complexes can occupy very large volumes. a. hyaluronidase b. hyaluronic acid c. proteoglycase d. fibronectin e. lamininarrow_forwardWhich of the following statements are acceptable and why? [Whereas all the carbohydrate in the plasma membrane faces outward on the external surface of the cell, all the carbohydrate on internal membranes faces toward the cytosol.] [Although lipid molecules are free to diffuse in the plane of the bilayer, they cannot flip-flop across the bilayer unless enzyme catalysts called phospholipid translocators are present in the membrane.]arrow_forward

If the concentration of glucose in a liver cell is higher than in the surrounding fluid, what mechanism could the cell use to import even more glucose?

- What is the function of coated vesicles?arrow_forwardSome scientists claim that prokaryotes like bacteria have membrane bound organelles, like chromatophores, anammoxosomes and magnetosomes. What really is the truth because it is widely known that prokaryotes do not have membrane bound organelles. Are these claims true or merely speculative? If this is true, what is the physiological basis for this?arrow_forwardPlasma cells are key to the immune response because they secrete antibodies. Given that antibodies are made of protein, which membrane enclosed cell organelle would you expect the plasma cells to have in abundance? Why?arrow_forward
