NC EOC Review: Biochemistry

Front

What are enzymes classified as?

Back

Enzymes are classified as proteins, which are a type of biomolecule that catalyze biochemical reactions.

Front

What type of bond connects the bases in a DNA molecule?

Back

Hydrogen bonds hold the DNA bases together in the double helix structure.

Front

What happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, it changes shape and loses its functional ability.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required for a chemical reaction to occur.

Front

How does the shape of an enzyme affect its function?

Back

The shape of an enzyme determines its function; a specific shape allows it to bind to its substrate effectively.

Front

What are the four main types of biomolecules?

Back

The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What is the role of enzymes in biochemical reactions?

Back

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

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule that an enzyme acts upon during a biochemical reaction.

Front

What is the significance of the active site of an enzyme?

Back

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

Front

What can cause an enzyme to denature?

Back

Factors such as extreme temperature, pH changes, and high concentrations of substrate can cause an enzyme to denature.
