The energy storage carbohydrates among the given options are:

  • Starch
  • Glycogen

Explanation for each option:

  1. Triglyceride: Incorrect. Triglycerides are a type of lipid, not a carbohydrate. They are used for long-term energy storage in animals but are not classified as carbohydrates.

  2. Starch: Correct. Starch is a polysaccharide carbohydrate that plants use to store energy. It is composed of glucose units and is a major energy reserve in plants.

  3. Phospholipid: Incorrect. Phospholipids are a type of lipid that make up the cell membrane. They are not used for energy storage and are not carbohydrates.

  4. Chitin: Incorrect. Chitin is a structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi. It is not used for energy storage.

  5. Cellulose: Incorrect. Cellulose is a structural polysaccharide found in the cell walls of plants. It provides structural support and is not used for energy storage.

  6. Glycogen: Correct. Glycogen is a polysaccharide carbohydrate that animals use to store energy. It is stored in the liver and muscle tissues and can be quickly mobilized to meet energy needs.

Summary: The energy storage carbohydrates are Starch and Glycogen.
