Answer:
Step-by-step explanation:
If glucose inside a cell needs to travel to another part of the body, it can leave the cell through a process called facilitated diffusion. Facilitated diffusion is a type of passive transport that allows substances to move across the cell membrane from an area of high concentration to an area of low concentration, without the need for energy input from the cell.
In facilitated diffusion, glucose moves through special protein channels called glucose transporters, which are embedded in the cell membrane. These transporters bind to glucose molecules and undergo a conformational change that allows them to transport the glucose molecule across the membrane. The transporters are specific to glucose and will only allow glucose to pass through, while other substances are excluded.
Once the glucose has entered the bloodstream through facilitated diffusion, it can travel to other parts of the body through the circulatory system. From there, glucose can enter other cells and be used for energy or stored as glycogen for future use.
It is important to note that the process of facilitated diffusion requires a concentration gradient to be present. If the concentration of glucose is the same inside and outside of the cell, there will be no net movement of glucose, and the glucose will remain inside the cell. Therefore, for facilitated diffusion to occur, there needs to be a concentration difference between the inside and outside of the cell.
