Passive Transport

Front

What is passive transport?

Back

Movement of substances across a cell membrane without an input of energy by the cell.

Front

Which of the following is a type of passive transport?

Back

Facilitated diffusion.

Front

What happens to an animal cell in a hypertonic solution?

Back

It shrinks.

Front

What is osmosis?

Back

The movement of water molecules from high to low concentration.

Front

In which type of solution does osmosis occur?

Back

All of the above (Hypotonic, Hypertonic, Isotonic).

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane proteins.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.

Front

What is an isotonic solution?

Back

A solution with an equal concentration of solutes compared to another solution.
