Exocytosis

Front

What is the process called when cells take in materials by engulfing them?

Back

Endocytosis

Front

What happens to cells when they are placed in pure water?

Back

They expand due to osmosis.

Front

What type of solution has the same concentration of solutes as the inside of a cell?

Back

Isotonic solution

Front

What is the term for the movement of molecules across a cell membrane via a protein channel, down their concentration gradient?

Back

Facilitated diffusion

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 osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What type of transport requires energy in the form of ATP?

Back

Active transport.

Front

What is the role of protein channels in facilitated diffusion?

Back

They provide a pathway for specific molecules to cross the cell membrane.

Front

What occurs during the process of phagocytosis?

Back

Cells engulf large particles or other cells.
