Carbon dioxide (CO2) exhibits which of the following membrane transport movements? it can cross the membrane by facilitated diffusion, because it is small, polar, and organic it can cross the membrane by simple diffusion, because it is small, nonpolar, and inorganic it cannot cross the membrane by passive transport, because it is large, polar, and organic it cannot cross the membrane by active transport, because it is large, polar, and inorganic it can cross the membrane by active transport, because it is large, nonpolar, and organic

Passive transport across the membrane mediated by a carrier— would not be saturated by increasing amount of substance to be transported. does not require energy (ATP). can be driven in reverse. moves the solute through the membrane in the “uphill” direction of their concentration gradient. is faster than transport mediated by channel proteins.

Which of the following statements about diffusion is correct? It is an active process in which molecules move from a region of lower concentration to one of higher concentration. It is very rapid over long distances. It requires an expenditure of energy by the cell. It is a passive process in which molecules move from a region of lower concentration to a region of higher concentration. It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.
