Which of the following best describes the field of biochemistry?

• A. The study of the physical properties of non-living matter.
• B. The study of the Earth's atmosphere and weather patterns.
• C. The study of the chemical processes and substances that occur within living organisms.
• D. The study of the structure and function of inorganic compounds.

Answer: (C)

Verified step by step guidance

1. Understand the scope of biochemistry: Biochemistry is a branch of science that focuses on the chemical processes and substances occurring within living organisms. It bridges biology and chemistry to explain life at a molecular level.
2. Eliminate incorrect options: Review each option and determine whether it aligns with the definition of biochemistry. For example, the study of non-living matter and inorganic compounds falls under other fields like physical chemistry or inorganic chemistry.
3. Focus on living organisms: Biochemistry specifically deals with molecules like proteins, nucleic acids, lipids, and carbohydrates, and their roles in processes such as metabolism, cell signaling, and genetic information transfer.
4. Compare with other sciences: Biochemistry is distinct from fields like meteorology (study of weather patterns) or geology (study of Earth's physical properties). This helps clarify its unique focus on life processes.
5. Select the correct answer: Based on the definition and scope of biochemistry, the correct description is 'The study of the chemical processes and substances that occur within living organisms.'
