Cell Transport Review

Front

What is the term for a solution that has a lower concentration of solutes compared to the inside of a cell?

Back

Hypotonic

Front

What is the primary reason active transport requires energy?

Back

The cell is moving substances against a concentration gradient.

Front

What is the process called when particles move from an area of lower concentration to an area of higher concentration?

Back

Active transport

Front

What is the term for the movement of molecules from an area of higher concentration to an area of lower concentration without the use of energy?

Back

Diffusion

Front

What type of transport does not require energy and occurs along the concentration gradient?

Back

Passive transport

Front

What is the role of ATP in active transport?

Back

ATP provides the energy needed to move substances against their concentration gradient.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell will lose water and shrink.

Front

What is the difference between facilitated diffusion and simple diffusion?

Back

Facilitated diffusion requires specific transport proteins, while simple diffusion does not.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.
