Study Notes
Definition of Biochemistry
- Biochemistry is the branch of science that explores the chemical processes within and related to living organisms.
- It combines principles of both biology and chemistry to understand biological functions at the molecular level.
Structural Unit of Living Systems
- The structural unit of living systems is the cell.
- Cells are the basic building blocks of life, containing necessary components like organelles, cytoplasm, and cell membrane.
Areas Encompassed by Biochemistry
- Biochemistry covers a wide range of areas including enzymology, molecular biology, genetics, and metabolism.
- It also studies carbohydrates, proteins, lipids, and nucleic acids, crucial for life functions.
Enzymatic Reactions
- Series of consecutive enzymatic reactions that produce specific products are known as metabolic pathways.
- These pathways are vital for transforming substrates into end products efficiently and regulated by enzymes.
Metabolism
- Metabolism refers to the totality of chemical reactions that occur within a living organism to maintain life.
- It includes catabolism (breaking down molecules for energy) and anabolism (synthesizing compounds needed for growth and repair).
