Cells and Cell Transport

Front

What kind of transport does not require energy?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy.

Front

What does equilibrium mean?

Back

Equilibrium refers to a state where each side is equal or balanced in concentration.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process where proteins help move molecules across the cell membrane.

Front

What does 'hydrophobic' mean?

Back

Hydrophobic means water fearing; it describes substances that do not associate with water.

Front

What is cytoplasm?

Back

Cytoplasm is the gel-like substance found in all cells that provides shape and support.

Front

What is active transport?

Back

Active transport is the movement of molecules against their concentration gradient, requiring energy.

Front

What is osmosis?

Back

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

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain molecules to pass while blocking others.

Front

What are the main components of the cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer, proteins, cholesterol, and carbohydrates.

Front

What is the role of proteins in the cell membrane?

Back

Proteins in the cell membrane assist in transport, act as receptors, and provide structural support.
