Starch is a homopolysaccharide that is important in human diets as it is a major source of carbohydrates. The end product formed from the complete digestion of starch is glucose, which is an important source of energy for the body. Therefore, option D, "starch; glucose" is the correct answer. Option A, cellulose, is also a homopolysaccharide, but humans lack the enzyme to digest it completely, so it does not provide significant nutritional value. Option B, lactose, is a disaccharide, and the end products of its digestion are glucose and galactose. Option C, glycogen, is a polysaccharide, but it is not obtained from the diet as it is synthesized and stored in the liver and muscle cells of animals.
