Macromolecules Vocabulary

The range of temperature and pH levels that an enzyme works best.

• polymer

• optimum

• substrate

• monomer

These macromolecules are used to store energy, waterproof, make up the cell membrane and communicate within the body

• Carbohydrates

• Protein

• Fats

• Nucleic Acids

A macromolecule found in food that helps to build cell walls, gives energy to animals and stores energy in plants

• Carbohydrates

• Proteins

• Fats

• Nucleic Acids

A type of protein that acts as a catalyst to lower activation energy in a chemical reactions in cells. This molecule not change and can be used over again.

• hemoglobin

• hormones

• amino acids

• enzymes

A polysaccharide carbohydrate consisting of a large number of glucose molecules.

• carbohydrate

• starch

• lipids

• protein

Made up of sub-units of fatty acids and used for structure and stored energy. Examples are fats, oils, and waxes.

• lipids

• proteins

• starch

• nucleic acids

Complex structure made of monomers

• Monomer

• Polymer

A macromolecule that is used to build cell structures, fibers, and muscle. It also makes enzymes which are proteins that help reactions take place in the body

• Carbohydrates

• Proteins

• Fats

• Nucleic Acids

The region of an enzyme where substrate molecules bind and undergo a chemical reaction.

• enzyme

• catalyst

• active site

• glucose

A molecule that fits into the active site of the enzyme. Can be called a reactant.

• enzyme

• substrate

• monomers

• nucleic acids
