Organic Molecules 2

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological substances that speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is the primary function of nucleic acids?

Back

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

Front

Which elements are essential for building carbohydrates?

Back

The essential elements for building carbohydrates are Carbon (C), Hydrogen (H), and Oxygen (O).

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in protein synthesis and can act as a messenger.

Front

What are macromolecules?

Back

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

Front

What is the structure of a nucleotide?

Back

A nucleotide consists of three components: a phosphate group, a five-carbon sugar, and a nitrogenous base.

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 function of carbohydrates in living organisms?

Back

Carbohydrates provide energy, serve as structural components, and are involved in cell recognition.

Front

What is the significance of nitrogen in biological molecules?

Back

Nitrogen is a key component of amino acids and nucleotides, which are the building blocks of proteins and nucleic acids, respectively.

Front

How do enzymes affect the rate of chemical reactions?

Back

Enzymes increase the rate of chemical reactions by providing an alternative reaction pathway with a lower activation energy.
