EXCESS carbohydrates are stored in the liver and muscles in the form of which of the following substances?

Rationale

Excess carbohydrates are stored in the liver and muscles in the form of glycogen.

Glycogen serves as the primary storage form of glucose in the body, allowing for a readily accessible energy source when blood glucose levels are low. Both the liver and muscles convert excess carbohydrates into glycogen through a process called glycogenesis.

A (Glucagon) YOUR ANSWER

Glucagon is a hormone produced by the pancreas that raises blood glucose levels by promoting the conversion of glycogen back into glucose in the liver. While it plays a crucial role in regulating blood sugar, it is not a storage form of carbohydrates, but rather a signaling molecule that activates glycogen breakdown.

B (Glucose) YOUR ANSWER

Glucose is a simple sugar that circulates in the bloodstream and is used by the body for immediate energy. While it is the primary product of carbohydrate digestion, it is not stored directly in the liver or muscles; instead, excess glucose is converted into glycogen for storage.

C (Glucoside) YOUR ANSWER

Glucosides are compounds formed from a sugar molecule and another substance (often a non-sugar molecule) through a glycosidic bond. They play various roles in plants and animals but are not involved in carbohydrate storage in the body.

D (Glycogen) CORRECT

Glycogen is a polysaccharide made up of numerous glucose units linked together, specifically designed for energy storage in animals. It is primarily found in the liver and muscles, where it is readily mobilized to meet energy demands when needed.

E (Glycoside) YOUR ANSWER

Glycosides refer to a class of compounds that consist of a sugar and another functional group. They are involved in various biochemical processes but do not function as a storage form of carbohydrates within the body.

Conclusion

The body stores excess carbohydrates primarily as glycogen in the liver and muscles, which provides a critical energy reserve. Other choices, such as glucagon, glucose, glucoside, and glycoside, serve different roles in metabolism but are not involved in carbohydrate storage. Understanding this distinction is vital for comprehending how the body manages energy resources efficiently.
