2. Final EOC Review - Macromolecules and Enzymes

Front

What is the optimum pH of an enzyme?

Back

The optimum pH of an enzyme is the pH at which it is most active. For example, an enzyme may have an optimum pH of 6.6.

Front

Which macromolecule is the main immediate source of energy for living organisms?

Back

Carbohydrates are the main immediate source of energy.

Front

What macromolecule is primarily responsible for long-term energy storage?

Back

Lipids/Fats are responsible for long-term energy storage.

Front

What is an enzyme?

Back

An enzyme is a special type of protein that acts as a catalyst to speed up chemical reactions.

Front

How does pH affect enzyme activity?

Back

Enzyme activity can increase or decrease depending on the pH level, with each enzyme having an optimum pH.

Front

What are the four main types of macromolecules?

Back

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

Front

What role do carbohydrates play in the body?

Back

Carbohydrates provide a quick source of energy for the body.

Front

What is the function of lipids in living organisms?

Back

Lipids serve as long-term energy storage, insulation, and make up cell membranes.

Front

What are proteins made of?

Back

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

Front

What is the structure of nucleic acids?

Back

Nucleic acids are made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
