Glucose moves from the plasma into a skeletal muscle cell, where it is used for energy. Through which fluid compartment does glu
cose move between the plasma and the skeletal muscle cell? A) Intracellular fluid
B) Interstitial fluid
C) Extracellular fluid inside of blood vessels
D) Cytosol
The intracellular fluid is a compartment that includes all fluid encapsulated in cells by their plasma membranes.
Extracellular fluid encircles all cells in the body. Extracellular fluid is sub-divided into two sections:
The Plasma: This is the fluid component of the blood. Plasma advances through the body in blood vessels and transports blood cells and other materials.
The interstitial fluid: They are found in spaces around the cells. They helps in transportation of materials between capillaries and cells in the Interstitial fluid e.g they directs oxygen and nutrients into the cells and helps to remove waste products from it.
Movement of Glucose is achieved by facilitated diffusion in the interstitisl fluid compartment.
Facilitated DIffusion is the movement of molecules across a membrane through a type of integral proteins that spans the entire cell membrane. (i.e whereby a molecule (e.g glucose molecule) move down a concentration gradient through specific protein channels in the membrane).
Now, the fluid through which glucose move between the plasma and the skeletal muscle cell is called the Interstitial Fluid, this because it is the pathway through which glucose molecule are carried to their target cell(i.e skeletal muscle cells) with the help of transport proteins.
It prevents displacement of the clasp into the gums the rest maintains the level of the clasp at which it engages the tooth surface. It serves as a reference pointfor evaluating fit of framework on the teeth.
