Cell Transport

Front

What is the process called when particles move from high to low concentration?

Back

Passive Transport

Front

What type of transport requires energy (ATP) to move substances across a cell membrane?

Back

Active Transport

Front

What happens to an animal cell when it is placed in a hypertonic solution?

Back

It shrinks (gets smaller).

Front

What is osmosis?

Back

A form of passive transport specifically for water molecules.

Front

What is the primary energy molecule used in active transport?

Back

ATP (Adenosine Triphosphate)

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What is a hypotonic solution?

Back

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

Front

What occurs during facilitated diffusion?

Back

Substances move across the cell membrane with the help of transport proteins, without using energy.

Front

What is the role of carrier proteins in active transport?

Back

They help move substances against their concentration gradient using energy.
