Cell Transport

Front

Movement of particles from high to low concentration.

Back

Passive Transport

Front

Osmosis is a form of ______________.

Back

Passive Transport

Front

Solutes move with the concentration gradient, therefore no energy is used.

Back

Passive Transport

Front

Movement of materials from high to low concentration through a protein channel.

Passive Transport

Front

ATP is a form of energy.

Back

Active Transport

Front

What is the primary difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy (ATP).

Front

Define osmosis.

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a concentration gradient?

Back

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

Front

What role do protein channels play in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane.

Front

What is active transport?

Back

The movement of substances against their concentration gradient, requiring energy.
