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 a readily available energy source 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 muscles. The liver stores glycogen to regulate blood glucose levels, while skeletal muscles store glycogen for energy during muscle activity.
Evaluate the options provided: Adipose tissue primarily stores fat (lipids) as an energy reserve, not glycogen. The pancreas is involved in producing insulin and glucagon for glucose regulation but does not store glycogen. Red blood cells lack organelles like mitochondria and nuclei, so they do not store glycogen either.
Focus on the liver: The liver is the correct answer because it plays a central role in glycogen storage and glucose homeostasis. Glycogen stored in the liver can be broken down into glucose and released into the bloodstream when needed.
Conclude the reasoning: Based on the biological functions of the tissues listed, the liver is the correct answer for glycogen storage, as it is specifically adapted for this purpose.
