What is diffusion?

Back

Diffusion is the process by which particles move from an area of high concentration to an area of low concentration until equilibrium is reached.

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 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 osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell; they generate ATP through cellular respiration.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus packages, modifies, and distributes proteins and lipids that have been synthesized in the cell.

Front

What are ribosomes?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the role of the nucleus?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.

Front

What is the endoplasmic reticulum?

Back

The endoplasmic reticulum (ER) is a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough ER (with ribosomes) and smooth ER (without ribosomes).

Front

What is a cell membrane?

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
