Cellular Transport

Front

What is the substance that is dissolved in a solution?

Back

The substance that is dissolved in a solution is called a solute.

Front

What term describes when there is the same concentration of solute molecules outside the cell as inside?

Back

This condition is referred to as isotonic.

Front

What happens to blood cells placed in a hypertonic solution?

Back

Blood cells placed in a hypertonic solution will lose water and shrink.

Front

What type of particle transport requires energy?

Back

Active transport requires energy.

Front

What does active transport require to function?

Back

Active transport requires energy.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solute compared to the inside of the cell, causing the cell to swell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solute compared to the inside of the cell, causing the cell to shrink.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is facilitated diffusion?

Back

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

Front

What is the role of the cell membrane in cellular transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
