Front

How does exocytosis help a cell maintain homeostasis?

Back

Cells must dispose of waste in order to maintain their homeostasis.

Front

What type of transport is endocytosis?

Back

Active Transport

Front

What is the process called when molecules move from high concentration to low concentration through a carrier protein?

Back

Facilitated Diffusion

Front

What is passive transport?

Back

The movement of molecules across the cell membrane without the use of energy.

Front

What is active transport?

Back

The movement of molecules across the cell membrane against the concentration gradient, requiring energy.

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

The process of transporting molecules across the cell membrane via protein channels without energy.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance across a space.
