Question

in which part of the body is glycogen stored?
liver
blood
pancreas
exoskeleton

Explanation:

Glycogen is a polysaccharide that serves as a form of energy storage in animals. The liver plays a crucial role in glycogen storage. When blood glucose levels are high (such as after a meal), the liver takes up glucose and converts it into glycogen for storage. When blood glucose levels drop (e.g., during fasting or exercise), the liver can break down glycogen back into glucose and release it into the bloodstream. The pancreas is involved in producing hormones like insulin and glucagon that regulate blood - glucose levels but does not store glycogen. Blood is a medium for transporting glucose and other substances but not a storage site for glycogen. An exoskeleton is an external skeletal structure found in some invertebrates (like insects) and has no relation to glycogen storage in the human body.

Answer:

liver
