Final answer:
The correct answer is glycogen. Glycogen is classified as a carbohydrate and is broken down by the enzyme pancreatic amylase in the process of digestion.
Step-by-step explanation:
The correct answer is c. glycogen. Glycogen is classified as a carbohydrate. It is a complex polysaccharide that is stored in the liver and muscles as a form of energy reserve.
In the process of carbohydrate digestion, the enzyme involved in breaking down glycogen into glucose is called pancreatic amylase. It is produced by the pancreas and plays a crucial role in the digestion of complex carbohydrates.
Other enzymes involved in carbohydrate digestion include amylase, maltase, sucrase, and lactase, each responsible for breaking down different types of carbohydrates into simple sugars.
