5
__________ is the diffusion of water through a semipermeable membrane.
facilitated diffusion
exocytosis
active transport
osmosis
6
Active transport
all of the answers are correct
moves materials against a concentration gradient
is usually done by transport proteins in the cell membrane
requires energy
7
Passive transport
moves particles against a concentration gradient.
requires energy.
doesn't require energy.
moves particles from a high to a low concentration.
8
Equilibrium is reached
when particles are evenly distributed through the space.
when movement of particles stops.
only during passive transport.
at the end of active transport.
