Membrane & Transport Warm-up

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to another solution, causing cells to lose water and shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to another solution, causing cells to gain water and swell.

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes compared to another solution, resulting in no net movement of water into or out of the cell.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structural support and protection, and it helps maintain the shape of the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via a protein channel, moving from high to low concentration.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving from high to low concentration.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (ATP) to move from low to high concentration.

Front

What role do carrier proteins play in cell membranes?

Back

Carrier proteins assist in the transport of specific substances across the cell membrane, often involved in facilitated diffusion and active transport.

Front

What happens to a red blood cell in pure water?

Back

A red blood cell will swell and potentially burst due to the influx of water in a hypotonic environment.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
