Front

Which of the following is NOT a type of passive transport? (Osmosis, Diffusion, Endocytosis, Facilitated Diffusion)

Back

Endocytosis

Front

What is diffusion?

Back

A net process of a molecule moving from a high concentration to low concentration.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy (ATP).

Front

What is osmosis?

Back

The diffusion of water across a semi-permeable membrane.

Front

What is facilitated diffusion?

Back

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

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is concentration gradient?

Back

The difference in concentration of a substance across a space.
