• Two leak-proof bags were set up. • One bag was made from artificial partially permeable membrane (Visking tubing). • The other bag was made from a piece of small intestine containing living cells, with its inner surface inside the bag. • The bags were filled with equal volumes of a dilute glucose solution. • The bags were suspended in the same glucose solution for two hours. • After two hours, the volumes of the bags were measured and the contents were tested for the concentration of glucose. Inside the bag made from small intestine the volume and concentration of the glucose solution decreased. There were no changes to the volume and concentration in the Visking tubing bag. (c) State and explain the process responsible for the decrease in the glucose concentration in the bag made from small intestine.
