Biology: Cell Transport: Kahoot

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is active transport?

Back

The process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of a cell, causing water to move into the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of a cell, causing water to move out of the cell.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is the sodium-potassium pump?

Back

An active transport mechanism that moves sodium ions out of the cell and potassium ions into the cell against their concentration gradients.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will lose water and shrivel due to the higher concentration of solutes outside the cell.

Front

What happens to a cell in a hypotonic solution?

Back

The cell will gain water and may swell or burst due to the lower concentration of solutes outside the cell.

Front

What is the role of carrier proteins in cell transport?

Back

Carrier proteins facilitate the movement of specific molecules across the cell membrane, either through passive or active transport.

Front

What is equilibrium in the context of cell transport?

Back

A state where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
