Cell Transport

Front

What is Exocytosis?

Back

A process where cells expel materials using energy, classified as Active Transport.

Front

Which processes use energy?

Back

Both endocytosis and exocytosis use energy.

Front

What is Passive Transport?

Back

Movement of materials from high to low concentration through a protein channel without using energy.

Front

What is Active Transport?

Back

Movement of materials against the concentration gradient (low to high) using energy (ATP).

Front

What does ATP stand for?

Back

Adenosine Triphosphate, the energy currency of the cell.

Front

What is the concentration gradient?

Back

The difference in concentration of a substance across a space.

Front

Define Osmosis.

Back

The passive transport of water molecules across a semipermeable membrane from high to low concentration.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses protein channels to help move substances across the cell membrane.

Front

What is endocytosis?

Back

A process where cells take in materials by engulfing them, requiring energy.

Front

What is the role of protein channels in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane, especially in passive transport.
