What is a hypotonic solution?

Back

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

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrivel.

Front

What is exocytosis?

Back

Exocytosis is the process by which cells expel materials, such as waste, by vesicles fusing with the cell membrane.

Front

What is the role of receptor proteins in cell signaling?

Back

Receptor proteins bind to signal molecules, triggering a response inside the cell, such as activating a second messenger.

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 a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of substances.

Front

What is the difference between passive and active transport?

Back

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

Front

What is a semipermeable membrane?

Back

A semipermeable membrane allows certain molecules or ions to pass through it while blocking others.
