Cell Transport

Front

What is the function of the cell membrane?

Back

The cell membrane helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

Front

What is diffusion?

Back

Diffusion is the movement of molecules across a membrane from high concentration to low concentration.

Front

What are the two types of cell transport?

Back

The two types of cell transport are Passive and Active transport.

Front

What role do cholesterols play in the cell membrane?

Back

Cholesterols increase the fluidity of the membrane.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane using energy, typically in the form of ATP.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, following the concentration gradient.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move molecules across the membrane.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy required for active transport to move substances against their concentration gradient.

Front

What are glycolipids?

Back

Glycolipids are lipids with carbohydrate chains that play a role in cell recognition and signaling.
