Verified step by step guidance
1
Understand the role of glycogen: Glycogen is a polysaccharide that serves as a storage form of glucose in animals. It is primarily stored in tissues that require quick access to energy or play a role in regulating blood glucose levels.
Identify the primary storage sites for glycogen: Glycogen is predominantly stored in the liver and skeletal muscle. The liver stores glycogen to regulate blood glucose levels, while skeletal muscle stores glycogen for energy during physical activity.
Evaluate the given tissue types: Epithelial tissue is primarily involved in covering surfaces and does not store glycogen. Adipose tissue stores energy in the form of fat, not glycogen. Cardiac muscle relies on fatty acids and glucose for energy but does not store significant amounts of glycogen.
Focus on the liver: The liver is the correct answer because it plays a central role in glycogen storage and glucose homeostasis. It can break down glycogen into glucose and release it into the bloodstream when needed.
Conclude the reasoning: Based on the biological functions of the tissues listed, glycogen is typically stored in the liver, making it the correct answer.
