Unit 1 SOL Review: Biomolecules

Front

What are the six elements of life essential for biomolecules?

Back

Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts that speed up biochemical reactions by lowering the activation energy.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds.

Front

How do enzymes affect the activation energy of a reaction?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What is a macromolecule?

Back

A macromolecule is a large complex molecule, such as proteins, nucleic acids, carbohydrates, and lipids, that are essential for life.

Front

What is the relationship between enzymes and substrates?

Back

Enzymes bind to substrates at their active sites to facilitate chemical reactions.

Front

What is a graph in the context of enzyme activity?

Back

A graph can represent the relationship between enzyme concentration, substrate concentration, and the rate of reaction.

Front

What happens to the rate of reaction when an enzyme is added?

Back

The rate of reaction increases when an enzyme is added, as it speeds up the reaction.

Front

What is the significance of constants in an experiment?

Back

Constants are variables that are kept the same throughout an experiment to ensure that the results are valid.

Front

What are the four main types of macromolecules?

Back

Proteins, nucleic acids, carbohydrates, and lipids.
