Question 2
Diffusion -
is an active process in which molecules move from a region of lower
concentration to one of higher concentration
requires an expenditure of energy by the cell
is a passive process in which molecules move from a region of higher
concentration to a region of lower concentration
requires integral proteins in the cell membrane
is very rapid over long distances
