Verified step by step guidance

Step 1: Understand the context of the question. The problem is asking for the molecule humans use to store carbohydrate energy. This requires knowledge of carbohydrate storage molecules in biochemistry.

Step 2: Review the options provided: Chitin, Starch, Glycogen, and Cellulose. Each of these molecules has distinct biological roles and is found in different organisms.

Step 3: Recall that Glycogen is the primary carbohydrate storage molecule in humans. It is a highly branched polysaccharide composed of glucose units, stored mainly in the liver and muscles.

Step 4: Eliminate the incorrect options: Chitin is a structural polysaccharide found in the exoskeletons of arthropods; Starch is a storage polysaccharide in plants; Cellulose is a structural polysaccharide in plant cell walls.

Step 5: Conclude that Glycogen is the correct answer based on its role in human carbohydrate energy storage.
