Cell Transport 2

Front

What happens to a cell in a hypertonic solution?

Back

Water moves from the inside of the cell to the solution, causing the cell to shrink.

Front

What is Facilitated Diffusion?

Back

It is the process where molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein.

Front

What occurs to a cell in a hypotonic solution?

Back

The cell will swell and perhaps burst (lyse) due to the influx of water.

Front

Define osmosis.

Back

Osmosis is the process where only water is allowed to pass through the cell membrane from a high to low concentration.

Front

What is the function of the cell membrane?

Back

The cell membrane helps maintain homeostasis by controlling what substances may enter or leave cells.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes outside the cell than inside, leading to water moving out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes outside the cell than inside, causing water to move into the cell.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What role do carrier proteins play in cell transport?

Back

Carrier proteins facilitate the movement of specific molecules across the cell membrane, especially during facilitated diffusion.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration without the need for energy.
