    glucose + glucose —> maltose by dehydration synthesis.
  • which statement best explains how the structure of a starch molecule relates to its function?
    The structure of a starch molecule, being a polysaccharide, allows it to store large amounts of glucose, which plants use for energy storage.
  • which of the following are functions of carbohydrates? (select all that apply)
    Functions of carbohydrates include structural support (e.g., cellulose in plants, chitin in animals) and energy storage (e.g., starch in plants, glycogen in animals).
  • what best describes the relationship between starch and glucose?
    Starch is a polysaccharide composed of many glucose units linked together, used by plants for energy storage.
  • what percentage of the total grams of carbohydrate in the cookie are sugars?
    To determine the percentage of sugars in the total grams of carbohydrate in the cookie, you would need the specific nutritional information of the cookie.
  • in which macromolecule will she use the black, red, and purple balls in a ratio of 1:2:1?
    The macromolecule is a carbohydrate, as the ratio 1:2:1 represents the general formula for simple carbohydrates (CnH2nOn).
  • which characteristic do glycogen and starch share?
    Both glycogen and starch are polysaccharides used for energy storage; glycogen in animals and starch in plants.
