Front

What are biomolecules?

Back

Biomolecules are organic molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the primary function of carbohydrates?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is the structure of a nucleic acid?

Back

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

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 30°C for many enzymes.

Front

What are lipids primarily used for in the body?

Back

Lipids are used for long-term energy storage, insulation, and making up cell membranes.

Front

What is the function of nucleic acids?

Back

Nucleic acids store and transmit genetic information.

Front

What are the two main types of nucleic acids?

Back

The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
