What do the biochemical processes studied in biochemistry primarily focus on?

• A. The study of celestial bodies and their movements
• B. The chemical reactions and molecular mechanisms occurring within living organisms
• C. The physical properties of non-living matter
• D. The geological formation of minerals and rocks

Answer: (B)

Verified step by step guidance

1. Biochemistry primarily focuses on understanding the chemical reactions and molecular mechanisms that occur within living organisms. This includes studying how biomolecules like proteins, nucleic acids, lipids, and carbohydrates interact and function.
2. The study of celestial bodies and their movements is related to astronomy, not biochemistry. It does not involve the molecular processes within living organisms.
3. The physical properties of non-living matter are studied in fields like physics and inorganic chemistry, which are distinct from biochemistry's focus on living systems.
4. The geological formation of minerals and rocks is the domain of geology, which deals with Earth's physical structure and processes, not the biochemical reactions in living organisms.
5. To summarize, biochemistry is centered on the chemical reactions and molecular mechanisms that sustain life, distinguishing it from other scientific disciplines like astronomy, physics, and geology.
