Cell Membrane Review

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and structural support.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What are lipids?

Back

Lipids are a group of organic compounds that are insoluble in water, including fats, oils, and phospholipids, which are essential components of cell membranes.

Front

What are proteins in the context of the cell membrane?

Back

Proteins in the cell membrane serve various functions, including acting as channels, receptors, and transporters for molecules.

Front

What are carbohydrates in the context of the cell membrane?

Back

Carbohydrates on the cell membrane play a role in cell recognition and communication, often attached to proteins or lipids.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to lose water and shrink.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to gain water and swell.
