Macromolecules ,Enzymes and Cells Review

Front

What is the active site of an enzyme?

Back

The active site is the specific region on an enzyme where the substrate binds and undergoes a chemical reaction.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including proteins, lipids, carbohydrates, and nucleic acids.

Front

What is the primary function of lipids in animal tissues?

Back

Lipids function in insulation, helping animals conserve heat.

Front

Which macromolecule is primarily used for short-term energy?

Back

Carbohydrates are primarily used for short-term (quick) energy.

Front

What is a substrate in the context of enzymes?

Back

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

Front

Why do enzymes only work with specific substrates?

Back

Enzymes only work with specific substrates because each substrate matches the active site on the enzyme.

Front

What is an example of a nucleic acid?

Back

An example of a nucleic acid is a strand of DNA.

Front

What are proteins made of?

Back

Proteins are made of amino acids linked together by peptide bonds.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions without being consumed in the process.

Front

What are carbohydrates primarily composed of?

Back

Carbohydrates are primarily composed of carbon, hydrogen, and oxygen.
