Verified step by step guidance

Understand the basic functions of carbohydrates in biological systems. Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, and they play several roles in living organisms.

Recognize that carbohydrates are primarily known for their role in energy storage. They are stored as glycogen in animals and starch in plants, which can be broken down to release energy when needed.

Identify the structural role of carbohydrates. They are key components of cell walls in plants (cellulose) and exoskeletons in arthropods (chitin), providing structural support.

Consider why carbohydrates do not function in information storage. Information storage is primarily the role of nucleic acids (DNA and RNA), not carbohydrates.

Understand why carbohydrates do not function in enzymatic catalysis. Enzymes are proteins that catalyze biochemical reactions, whereas carbohydrates do not have this function.
