Cellular Transport

Front

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

Back

Isotonic

Front

What type of transport involves molecules moving from high to low concentration without the use of energy?

Back

Passive transport

Front

What is the overall goal of all cellular transport?

Back

To maintain homeostasis

Front

What distinguishes active transport from passive transport?

Back

Active transport uses energy.

Front

What is the function of the plasma membrane?

Back

To control what enters and exits the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solute compared to the inside of the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solute compared to the inside of the cell.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the role of transport proteins in cellular transport?

Back

To facilitate the movement of substances across the plasma membrane.

Front

What is the difference between diffusion and facilitated diffusion?

Back

Diffusion is the movement of molecules from high to low concentration, while facilitated diffusion requires a transport protein.
