Requires energy; vacuole fuses with membrane, contents forced out of cell = ?
exocytosis
phagocytosis
pinocytosis
endocytosis
5
What kind of transport doesn't require the use of energy to move materials across the membrane?
facilitated diffusion
all of these don't require the cell to use energy
osmosis
diffusion
6
Passive transport
moves particles from a high to a low concentration.
requires energy.
doesn't require energy.
moves particles against a concentration gradient.
7
Equilibrium is reached
at the end of active transport.
only during passive transport.
when particles are evenly distributed through the space.
when movement of particles stops.
8
Active transport
moves materials against a concentration gradient
all of the answers are correct
requires energy
is usually done by transport proteins in the cell membrane
