Question

the osmotic pressure Of a liver cell is 6atm. In response to insulin, liver cells take up glucose and concomitantly expand in size. How much glucose can a liver cell take up if it increases 10% in volume, while remaining isotonic? (Approximate liver cell volume based on eukaryotic cell size). If it stores this as 30000-glucose-units-long glycogen polymers while main ting its osmolarity, what will its size be? the osmotic pressure Of a liver cell is 6atm.

Explanation / Answer

osmotic pressure = 6 atm

glucose molar mass = 180 g / mol

suppose initial volume = 1 L

after 10 % increase volume = 1. 1 L

S = 0.0821 L -atm / mol K

T = 25 +273 = 298 K

P V = n S T

P V = W S T / M

W = P V M / S T

    = 6 x 1.1 x 180 / 0.0821 x 298

    = 48.56 g

glucose weight = 48.56 g
