9 Questions
Which process involves the movement of molecules from an area of higher concentration to an area of lower concentration without the use of a carrier molecule?
Simple diffusion
In facilitated diffusion, how do important molecules enter the cell?
Through specific protein channels or carrier proteins
What is the effect of a hypertonic solution on water molecules?
They tend to move out of the cell via osmosis
Which type of solution has the same water potential as the inside of the cell?
Isotonic solution
What distinguishes facilitated diffusion from simple diffusion?
Facilitated diffusion uses carrier proteins or specific channels
What happens in a hypotonic solution?
Water molecules tend to move into the cell via osmosis
How does water move during osmosis?
From a solution with lower water potential to higher water potential
Which statement about hypotonic solutions is accurate?
The solution contains fewer solutes than the inside of the cell
What characterizes isotonic solutions?
(Isotonic Solutions) No net movement of water.
