Cell Transport

Front

What is cell transport?

Back

Cell transport refers to the movement of substances into and out of cells, which is essential for maintaining homeostasis.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane.

Front

What is active transport?

Back

Active transport is the movement of molecules against their concentration gradient, requiring energy (ATP) to do so.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through 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 cell membrane?

Back

The cell membrane controls what enters and exits the cell, maintaining the internal environment.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

What are transport proteins?

Back

Transport proteins are proteins that help move substances across the cell membrane.

Front

What is endocytosis?

Back

Endocytosis is the process by which cells take in substances by engulfing them in a vesicle.
