Cell Transport GEN

Front

What happens to a cell placed in a hypotonic solution?

Back

The cell will swell (get bigger) due to water entering the cell.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses a transport protein to help move substances across the cell membrane.

Front

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy (ATP) to pump molecules in or out of the cell.

Front

What is diffusion?

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What occurs when a blood cell is placed in an isotonic solution?

Back

Water moves equally in and out of the cell, maintaining cell size.

Front

What is the role of transport proteins in cell transport?

Back

Transport proteins assist in moving substances across the cell membrane, especially in facilitated diffusion.

Front

What is the difference between passive and active transport?

Back

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

Front

What is an example of a substance that moves via osmosis?

Back

Water is the primary substance that moves through osmosis.

Front

What is the significance of concentration gradients in cell transport?

Back

Concentration gradients drive the movement of substances; molecules move from high to low concentration in passive transport.
