Cell Membrane and Transport Review

Front

What is the structure that forms the basic framework of the cell membrane?

Back

Phospholipid Bilayer

Front

What type of transport does not require energy to move substances across the cell membrane?

Back

Passive Transport

Front

What is the process called when molecules move from an area of high concentration to an area of low concentration without energy?

Back

Diffusion

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to move molecules across the cell membrane from high to low concentration.

Front

What role do transport proteins play in the cell membrane?

Back

They act as channels to allow certain objects to pass in and out of the cell.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is phagocytosis?

Back

A type of active transport where the cell engulfs large particles or cells.

Front

What is the function of cholesterol in the cell membrane?

Back

It helps to stabilize the membrane's fluidity.

Front

What are carbohydrate chains on the cell membrane used for?

Back

They are involved in cell recognition and signaling.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.
