Quizplus · Accepted Answer

Sucrose is a disaccharide composed of glucose and fructose. Therefore, when it is digested in the gastrointestinal tract, it is broken down into glucose and fructose molecules. Option A is incorrect because maltose and glycogen are not components of sucrose or products of its digestion. Option B is incorrect because alanine and aspartic acid are amino acids, not carbohydrates found in doughnuts. Option D is incorrect because glycerol and fatty acid are components of lipids, not carbohydrates found in doughnuts.
