Final answer:

Glucose moves from the plasma, through the interstitial fluid, which surrounds cells, to reach the skeletal muscle cells where it's used for energy. The correct answer is (B).

Step-by-step explanation:

The movement of glucose from the plasma into a skeletal muscle cell follows a specific path through different fluid compartments in the body. After digesting carbohydrates, glucose is absorbed into the bloodstream and circulates in the blood plasma. From here, glucose must then pass through the interstitial fluid that surrounds the cells. This movement is facilitated by a concentration gradient, where glucose levels are higher in the blood compared to inside the cells, and by glucose transport proteins present in the cell membrane. Thus, the correct answer is (B) Interstitial fluid, as the glucose moves from the plasma, through the interstitial space, and finally into the skeletal muscle cells where it can be utilized for energy production.

It is important to note that insulin plays a significant role in this process by stimulating the uptake of glucose into cells, particularly into liver and muscle cells for storage and energy use. Additionally, the sodium-potassium pump and facilitated diffusion mechanisms are involved in maintaining proper electrolyte balance and glucose transport, respectively.

Answer:

(B) Interstitial fluid

Step-by-step explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.
