The Grade 12 Bio students are learning about digestion in their Physiology lesson. The experiment of dialysis tubing demonstrates how nutrients are absorbed from the intestine after food is digested. The dialysis tubing is selectively permeable, mimicking the cells lining the intestine that absorb the nutrients and transport it to the blood stream. In this experiment, starch and amylase are mixed and kept in the dialysis tubing. As a result of digestion, maltose is produced and that passes through the tubing into the water outside. Testing the maltose is done with Benedict’s solution.
