Its energy source is glucose, which it is taking up from its environment via na/glucose symporters distributed throughout the surface of its plasma membrane. by briefly adding an inhibitor of all glucose breakdown, you are able to determine that glucose accumulates in the cell at the rate of 45 μm/hr. based on this number, how many μmoles of glucose must be entering the cell per hour? (assume that one-half of the volume of the cell is composed of organelles, and thus not available for diffusion of glucose)

The average time it takes for a molecule to diffuse a distance of x cm is given by t=x^2/2d where t is the time in seconds and d is the diffusion coefficient. given that the diffusion coefficient of glucose is 5.7 x 10^-7 cm2/s, calculate the time it would take for a glucose molecule to diffuse 10 pm, which is roughly the size of a cell.

Glucose is an important biomolecule. which of these statements is true regarding the movement of glucose into and out of cells? a) glucose, a small molecule, can diffuse between the phospholipids. b) glucose requires both a membrane protein and atp energy in order to enter or exit a cell. c) glucose, a nonpolar molecule, can pass freely across the phospholipid bilayer from high to low concentration. d) glucose is a large, hydrophilic molecule and must use a channel protein to enter or exit a cell, but does not require energy.
