1st Quarter - 5 Station Review

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What is the main macromolecule represented by carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and they serve as a primary energy source.

Front

What does a selectively permeable membrane do?

Back

A selectively permeable membrane allows some substances to pass through while blocking others, maintaining the internal environment of the cell.

Front

What is the equation for cellular respiration?

Back

C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, used to store and transfer energy.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What are the four major types of macromolecules?

Back

The four major types of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are catalysts that speed up chemical reactions in the body by lowering the activation energy required.

Front

What is the function of the cell membrane?

Back

The cell membrane protects the cell, provides structure, and regulates what enters and exits the cell.

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.
