Macromolecules and enzymes

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

True or False: Enzymes can only be used once in a chemical reaction.

Back

False. Enzymes can be used multiple times as they are not consumed in the reaction.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What macromolecule carries hereditary information?

Back

Nucleic acid.

Front

What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates and serve as the monomers for more complex carbohydrates.

Front

What is the function of catalysts in chemical reactions?

Back

Catalysts lower the activation energy of a chemical reaction, thereby increasing the reaction rate.

Front

What are the four main types of macromolecules?

Back

Carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What are lipids primarily composed of?

Back

Lipids are primarily composed of fatty acids and glycerol.

Front

What is the difference between a monomer and a polymer?

Back

A monomer is a single building block, while a polymer is a chain of monomers linked together.
