Front

What is the relationship when one organism is helped and one is hurt?

Back

Parasitism: A symbiotic relationship where one organism benefits at the expense of another.

Front

What is the process of moving molecules against the concentration gradient called?

Back

Active transport: The movement of molecules from an area of lower concentration to an area of higher concentration, requiring energy.

Front

What are the building blocks (monomers) of carbohydrates?

Back

Monosaccharides: Simple sugars that are the basic units of carbohydrates.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required.

Front

What are the building blocks (monomers) of nucleic acids?

Back

Nucleotides: The basic units that make up nucleic acids like DNA and RNA.

Front

What is mutualism?

Back

Mutualism: A symbiotic relationship where both organisms benefit.

Front

What is commensalism?

Back

Commensalism: A symbiotic relationship where one organism benefits and the other is neither helped nor harmed.

Front

What is passive transport?

Back

Passive transport: The movement of molecules across a cell membrane without the use of energy, typically from high to low concentration.

Front

What is diffusion?

Back

Diffusion: The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

Osmosis: The diffusion of water molecules through a selectively permeable membrane.
