What is the definition of concentration in a solution?

Back

Concentration refers to the amount of a substance (solute) present in a given volume of solution.

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solute compared to another solution, leading to water moving into cells.

Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane against their concentration gradient, requiring energy.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, a cell loses water and shrinks due to the higher concentration of solute outside the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy required for active transport to move molecules against their concentration gradient.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves molecules down their concentration gradient, while active transport requires energy to move molecules against their gradient.

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solute compared to another solution, resulting in no net movement of water.
