If additional galactose is added then reaction will move in backward direction to produce more Lactose. As a result more of D- glucose will get consumed. Hence, concentration of glucose decrease.
Correct option is : b) The glucose concentration will go down.

2. Lactose is a disaccharide sugar composed of galactose and glucose that is found in milk. But how can we determine the order that the glucose and galactose are connected in this disaccharide? Use your knowledge of reactions from CHE 128 (e.g. alcohols, aldehydes and hemi-acetals) to propose an experiment (i.e. a series of reactions or experiments) that will answer this question.
