Question

the diagram shows a straight chain of glucose molecules. which carbohydrate is shown above? fructose sucrose galactose starch

Explanation:

The diagram shows a straight chain of glucose molecules. Starch is a polysaccharide made of many glucose units linked in chains. Fructose is a monosaccharide (single sugar), sucrose is a disaccharide (two sugars: glucose + fructose), and galactose is a monosaccharide. So the carbohydrate with a chain of glucose is starch.

Answer:

starch (the option with "starch" label)
