Biomolecules and Enzymes

Front

What are biomolecules?

Back

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

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 primary function of carbohydrates?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What are lipids and their functions?

Back

Lipids are biomolecules that include fats, oils, and waxes, primarily used for energy storage, insulation, and making up cell membranes.

Front

What are proteins made of?

Back

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

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon during a chemical reaction.

Front

Explain the 'lock and key' model of enzyme action.

Back

The 'lock and key' model suggests that each enzyme (the lock) is specific to a particular substrate (the key), fitting together perfectly.

Front

What are nucleic acids and their primary function?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and stores genetic information, while RNA is single-stranded and plays a role in protein synthesis.
