Cellular Transport

Front

What is the primary function of the cell membrane?

Back

To maintain homeostasis by controlling what enters and exits the cell.

Front

What is exocytosis?

Back

The process by which vesicles remove substances from inside the cell.

Front

What are the main components of the cell membrane?

Back

Lipids, proteins, and carbohydrates.

Front

What is facilitated diffusion?

Back

A type of passive transport that does not require energy and uses protein channels to help molecules cross the membrane.

Front

What is the overall goal of cellular transport?

Back

To maintain homeostasis within the cell.

Front

What is endocytosis?

Back

The process by which cells take in substances by engulfing them in a vesicle.

Front

What role do lipids play in the cell membrane?

Back

They form the basic structure of the membrane, creating a barrier that separates the inside of the cell from the outside.

Front

What is the difference between passive and active transport?

Back

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

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space, which drives the movement of molecules during diffusion.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.
