Question

When the concentration of solutes is the same on both inside and outside cells, then: A) water leaves the cells B) water rushes into the cells C) water flows out of the cells into the transcellular environment D) the osmotic pressure is zero

Answer 1

In an isotonic solution, when the concentration of solutes is the same inside and outside the cells, there is no net movement of water into or out of the cells.

Step-by-step explanation:

In an isotonic solution, the extracellular fluid has the same osmolarity as the cell, resulting in no net movement of water into or out of the cell. When the concentration of solutes is the same inside and outside the cells, the cells maintain their normal shape and function. There is a balance of water movement in both directions, with water entering and leaving the cells at the same rate.
