Cell Activities

the process by which molecules, atoms, or ions diffuse through a semipermeable membrane down their concentration gradient

a type of passive transport that uses specialized proteins, such as channel proteins and carrier proteins, to help molecules move across a cell membrane

the net movement of water across a semipermeable membrane

a solution that has a higher concentration of solute than another solution

a solution that has a lower concentration of solute than another solution

the state when two solutions have equal concentration of solutes across a semipermeable membrane

the molecules are moved across the cell membrane, pumping the molecules against the concentration gradient using ATP

the active process in which a cell forms internal vesicles by invaginating its plasma membrane, allowing the absorption of various molecules and macromolecules from the extracellular fluid.

a process the cell uses to release molecules inside vesicles from the inside of the cell to the environment
