Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel waste materials or secrete substances by vesicles fusing with the plasma membrane.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell and potentially burst.

Front

What is a hypertonic solution?

Back

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

Front

What is an isotonic solution?

Back

An isotonic solution has an equal concentration of solutes inside and outside the cell, resulting in no net movement of water.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the plasma membrane?

Back

The plasma membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What occurs during endocytosis?

Back

Endocytosis is the process by which cells engulf external substances, bringing them into the cell within vesicles.

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.
