Question

which of the following is true?
starch is made of many glucose molecules.
starch is made of two glucose molecules.
starch is not made of glucose molecules.
glucose is made of many starch molecules.

Explanation:

Starch is a polysaccharide. Polysaccharides are made up of many monosaccharide units. Glucose is a monosaccharide. Starch is composed of many glucose molecules linked together. Two glucose molecules form a disaccharide (e.g., maltose). And it's starch that is made of glucose, not the other way around.

Answer:

Starch is made of many glucose molecules.
