Cell membrane spends energy in
Movement of solute from higher to lower concentration
Movement of solute from lower to higher concentration
Movement of solvent
All of these
Movement of solute from lower to higher concentration needs energy in the form of ATP.It is called as active transport.
Question 6 Which among the following defines osmosis the best? (a) Movement of water molecules from a region of higher concentration to a region of lower solute concentration through a semipermeable membrane (b) Movement of solvent molecules from its higher concentration to a lower concentration (c) Movement of solvent molecules from a higher concentration to a lower concentration of solution through a permeable membrane (d) Movement of solute molecules from a lower concentration to a higher concentration of a solution through a semipermeable membrane
If osmosis is the movement of solvent only from higher concentration to lower concentration then how did the semi permeable membrane stop the flow of solvent from lower concentration to higher concentration?
