Transcript text: Which of the following are energy storage carbohydrates? (check all that apply)
Triglyceride
Starch
Phospholipid
Chitin
Cellulose
Glycogen
Solution
The energy storage carbohydrates among the given options are:
Starch
Glycogen
Explanation for each option:
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.
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.
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.
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.
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.
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.
