Suppose a cell contains the same solutes in the intercellular fluid that are found in the extracellular fluid, but in different concentrations. Propose a way for substance
A to move from outside of the cell to inside. Be specific on the type of transport, how this transport occurs, and what energy is required.

Respuesta :

A way for substance A to move from outside of the cell to inside is osmosis (a kind of passive transport) with no such requirement of energy.

Osmosis is the passage of water molecules from a region of higher concentration to a region of lower concentration through a selectively permeable membrane. Water enters and exits cells via osmosis.  Until the exterior solution and the cytosol are isotonic, cells placed in a hypotonic solution will take in water across their membrane.

In reality, osmosis is a form of passive transport. Cells shrink when placed in hypotonic solution.  Energy is not needed. Particles travel from areas of high concentration to areas of low concentration in this process. A semi-permeable membrane allows only the solvent to pass through it (solute does not move).
