EOC Cell Membrane Transport Review

Front

What are the main components of the cell membrane?

Back

The main components of the cell membrane are phospholipids, proteins, cholesterol, and carbohydrates.

Front

What is the function of channel proteins in the cell membrane?

Back

Channel proteins facilitate the transport of specific substances across the cell membrane.

Front

Define passive transport.

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically along a 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 substances across the cell membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy (ATP) to do so.

Front

Name two types of active transport.

Back

Endocytosis and exocytosis are two types of active transport.

Front

What is the lipid bilayer?

Back

The lipid bilayer is a double layer of phospholipids that makes up the fundamental structure of the cell membrane.

Front

What role do glycoproteins play in the cell membrane?

Back

Glycoproteins are involved in cell recognition and signaling.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of solutes from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water.
