Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
- Isotonic solutions are solutions that have the same concentration of water on both sides of a cell membrane.
- In this case, the blood is an aqueous fluid that exhibits isotonic properties compared to its surrounding cells.
- Isotonicity enables the blood to transport oxygen and nutrients to the cells but simultaneously conserves the structure and form of these cells.
In conclusion, blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
