Which of the following polysaccharide is present in human muscles abundantly?

Explanation

Myoglobin: Myoglobin is a protein found in muscle tissues that is responsible for storing and transporting oxygen within muscle cells. While myoglobin is abundant in muscle tissues, it is not a polysaccharide. Actin and myosin: Actin and myosin are proteins that are major components of muscle fibers and are involved in muscle contraction. They are not polysaccharides. Collagen: Collagen is the most abundant protein in the human body and is a major component of connective tissues, such as tendons, ligaments, and skin. While it plays a crucial role in supporting and connecting tissues, collagen is not a polysaccharide. Glycogen: The correct option is d) Glycogen. Glycogen is a highly branched polysaccharide made up of glucose units and serves as the primary energy storage polysaccharide in animals, including humans. In human muscles, glycogen is stored in large amounts and acts as a readily available source of glucose during periods of increased energy demand, such as exercise. When energy is needed, glycogen is broken down into glucose units, which can be further utilized through cellular respiration to produce energy for muscle contraction and other cellular functions.In summary, the polysaccharide present in human muscles abundantly is d) Glycogen. It serves as an essential energy reserve that can be mobilized to meet the energy needs of muscle cells during physical activity and other energy-demanding processes.
