Biology: Cell Transport: Kahoot

Front

What is osmosis?

Back

The movement of water down a concentration gradient across a selectively permeable membrane.

Front

What is active transport?

Back

The process of moving molecules against their concentration gradient, requiring energy (ATP).

Front

What is the sodium-potassium pump?

Back

An example of active transport that moves sodium ions out of the cell and potassium ions into the cell.

Front

What is facilitated diffusion?

Back

The process of moving molecules across a membrane via transport proteins, down their concentration gradient.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrivel due to water moving out of the cell.

Front

What is a hypotonic solution?

Back

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

Front

What is isotonic solution?

Back

A solution with the same concentration of solutes as the inside of the cell, resulting in no net movement of water.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What role do carrier proteins play in cell transport?

Back

They assist in the movement of specific molecules across the cell membrane, often in active transport.

Front

What is the concentration gradient?

Back

The difference in the concentration of a substance across a space.
