During the time that the particles are diffusing into the cell, _____ a point is eventually reached where equal numbers of particles are passing into and out of the cell the rate of diffusion begins slowly, but eventually accelerates the concentration of particles on the outside of the cell increases the rate of diffusion remains constant concentration of particles on the outside of the cell decreases

Solution

Answer: (a)

A point is eventually reached where equal numbers of particles are passing into and out of the cell.

Diffusion is the process that causes these molecules to move in or out of the cell. Diffusion is driven by the random movements of individual molecules in solution. If the concentration of a molecule is greater outside a cell than inside the cell then, on average, more molecules will randomly enter the cell, than leave the cell.

Molecules that are capable of diffusion across a cellular membrane will eventually reach equal concentrations inside and outside of the cell. At this point the rate at which individual molecules enter and leave will be equal.
