Cell Transport

Front

What is Facilitated Diffusion?

Back

A type of passive transport that allows molecules to cross membranes with the assistance of special proteins.

Front

What is Active Transport?

Back

The process by which cells move molecules from an area of low concentration to an area of high concentration, requiring energy.

Front

What are the types of Passive Transport?

Back

1. Simple Diffusion 2. Facilitated Diffusion 3. Osmosis.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a Selectively Permeable Membrane?

Back

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

Front

What is Exocytosis?

Back

The process by which a cell expels large quantities of materials, such as toxins and waste.

Front

What is Endocytosis?

Back

The process by which a cell takes in materials by engulfing them in a membrane.

Front

What is Simple Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration without the need for energy.

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 the role of transport proteins in Facilitated Diffusion?

Back

Transport proteins help specific molecules cross the cell membrane without using energy.
