Which one is the definition of active transport?
movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.
passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane
net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient
net movement of molecule from a region of lower concentration to region of higher concentration. Molecule down a concentration gradient
What might happen if a cell did not have any ATP/energy?
It would not have enough energy to do active transport
It's cell membrane would break
The transport proteins would not be needed.
In active transport, .............
energy is required
energy is not required
Simple Diffusion
Facilitated diffusion
During active transport, what is required to move materials across the cell membrane?
water
energy
oxygen
cytoplasm
What term is used when the concentrations of solutes inside and outside a cell are in equilibrium?
hypotonic
isotonic
hypertonic
polytonic
What is the process by which water passes into or out of a cell?
dispersion
phagocytosis
osmosis
