Active transport occurs across which type of membranes?
A) Membranes that have a higher concentration of the solute on the outside of the cell
B) Membranes that are semipermeable to water and small electrically uncharged molecules
C) Membranes that have receptors that are capable of binding with the substances to be transported
D) Membranes that have a cell membrane that is hydrophobic rather than hydrophilic

Question

Quizplus · Accepted Answer

Some molecules are moved into the cell by mechanisms of active transport,which require receptors that are capable of recognizing and binding with the substance to be transported.Diffusion is the movement of a solute molecule from an area of greater solute concentration to an area of lesser solute concentration.Hydrostatic pressure is the mechanical force of water pushing against cellular membranes.Osmosis is the movement of water down a concentration gradient; that is,across a semipermeable membrane from a region of higher water concentration to a lower water concentration
