2. Consider four spherical cells with the diameters given in the table below. Based on estimates from the scientific literature, the cytoplasm in cells can require 100,000 molecules of glucose per per second. These cells use a protein on the cell surface called the glucose transporter (Glu) to transport glucose from the outside of the cell into the cytoplasm. Scientific measurements indicate that under normal conditions each Glutr has a transport rate capacity of around 400 molecules per second. Each...

_____membranes proteins are associated with the bilayer through interactions with other membrane component on the surface of the membrane. Net movement of particles from a region where they are more concentrated to a region where they are law concentrated is called Diffusion of water through a selectively permeable membrane down its own concentration gradient It called A solution with an equivalent concentration of water and hence the tame osmotic pressure as the fluid inside the cell is said to be...
