Biology EOC Review 4 (Organics/Cell Energy)

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that increase the reaction rate by lowering the activation energy required for the reaction to occur.

Front

What organic molecules are primarily responsible for long-term energy storage in living organisms?

Back

Lipids are the organic molecules used for long-term energy storage.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide is made up of a phosphate group, a deoxyribose sugar, and a nitrogenous base (such as guanine).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis takes place in the chloroplasts of plant cells.

Front

What class of biomolecules do DNA and RNA belong to?

Back

DNA and RNA belong to the class of biomolecules known as nucleic acids.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is used to convert carbon dioxide and water into glucose and oxygen.

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates serve as a primary source of energy and are also involved in structural functions.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
