Requires energy; vacuole fuses with membrane, contents forced out of cell = ?
exocytosis
endocytosis
pinocytosis
phagocytosis
6
What kind of transport doesn't require the use of energy to move materials across the membrane?

hydroponic
isotonic
hypotonic
hypertonic
17
Equilibrium is reached
when particles are evenly distributed through the space.
at the end of active transport.
only during passive transport.
when movement of particles stops.
18
Active transport
moves materials against a concentration gradient
is usually done by transport proteins in the cell membrane
all of the answers are correct
requires energy
19
The primary function of the cell membrane is
to protect the cell
cell signaling.
to control what moves in and out of the cell.
to provide support for the cell.

requires energy.
doesn't require energy.
moves particles from a high to a low concentration.
moves particles against a concentration gradient.
