What is the role of catalase in biological reactions?

Back

Catalase is an enzyme that breaks down hydrogen peroxide into water and oxygen, and it remains unchanged after the reaction.

Front

What biomolecule is primarily responsible for insulation and long-term energy storage?

Back

Lipid.

Front

Which biomolecule includes fats, oils, and waxes?

Back

Lipids.

Front

What does a semipermeable membrane do?

Back

It allows certain molecules to pass through while blocking others.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the movement of solute 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 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 the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What are the products of the reaction catalyzed by catalase?

Back

Water (H2O) and oxygen (O2).
