Answer:
glucose
Muscle cells are reservoirs for glucose, which is required for metabolic energy requirements. The skeletal muscles are the main sites where uptake of glucose and its storage occurs in conjunction with other muscle tissues.
Muscle cells functions as a reservoir for glucose.
• The prime source of fuel for the cells in the body is glucose.
• When the body does not require to utilize the glucose for energy, it get stores in the muscles and liver.
• The stored form of glucose is formed of several associated molecules of glucose and is known as glycogen.
• The main site for the uptake and storage of glucose is the cells of skeletal muscles.
• Glucose is an essential fuel for muscle contraction, and usual metabolism of glucose is essential for health. The entry of glucose within the cells of muscles takes place through facilitated diffusion via the GLUT4 glucose transporter.
Thus, muscle cells serve as a reservoir for glucose.
