Cellular Transport Flashcard

Front

What is the term for when the number of molecules of a substance are equal on either side of a cell membrane?

Back

Equilibrium

Front

What happens to a cell when it is placed in a hypertonic solution, such as extremely salty water?

Back

Water would leave the cell, causing it to shrink.

Front

What is the process called that involves the movement of water across a semipermeable membrane?

Back

Osmosis

Front

In passive transport, in which direction do molecules tend to move?

Back

From high concentration to low concentration.

Front

What type of cellular transport does not require energy from the cell?

Back

Passive transport.

Front

What is the difference between passive transport and active transport?

Back

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

Front

What is a semipermeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the term for a solution with a lower concentration of solutes compared to another solution?

Back

Hypotonic solution.

Front

What is the term for a solution with a higher concentration of solutes compared to another solution?

Back

Hypertonic solution.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to help move molecules across the cell membrane.
