Cell Transport

Front

What is the process called when a molecule moves from an area of high concentration to an area of low concentration?

Back

Diffusion

Front

What is the term for the movement of molecules against a concentration gradient?

Back

Active transport

Front

What is a hypertonic solution?

Back

A solution that has a higher osmotic pressure than another solution; it has a concentration of solutes greater than the concentration of solutes in the cells.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink.

Front

What is the term for the diffusion of water across a semi-permeable membrane?

Back

Osmosis

Front

What is the main difference between passive transport and active transport?

Back

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

Front

What is isotonic solution?

Back

A solution that has the same osmotic pressure as another solution, resulting in no net movement of water into or out of the cell.

Front

What is the role of the cell membrane in transport processes?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the significance of concentration gradients in cell transport?

Back

Concentration gradients drive the movement of substances across membranes, influencing diffusion and osmosis.
