Verified step by step guidance
1
Understand the definition of biomolecules: Biomolecules are organic molecules that are essential for life processes. They include carbohydrates, proteins, lipids, and nucleic acids, which are crucial for the structure and function of living organisms.
Differentiate between organic and inorganic compounds: Organic compounds contain carbon and are typically found in living organisms, whereas inorganic compounds do not necessarily contain carbon and are often found in non-living systems.
Consider the role of synthetic polymers: Synthetic polymers are man-made and used in industrial applications, which distinguishes them from naturally occurring biomolecules.
Evaluate the use of radioactive elements: Radioactive elements are used in medical imaging and are not considered biomolecules, as they do not play a direct role in life processes.
Identify the correct description: Based on the definitions and roles, the best description of biomolecules is 'Organic molecules that are essential for life processes.'
