Study Notes
Introduction to Biochemistry
- Friedrich Wöhler's 1828 experiment synthesized urea from ammonium cyanate, disproving the notion that organic compounds can only be produced by living organisms.
- Biochemistry studies the chemistry of living organisms, focusing on biological processes at cellular and molecular levels.
Importance of Biochemistry
- Serves as the foundation for understanding various biological processes.
- Helps explain the causes of diseases in humans, animals, and plants.
Chemical Foundations of Life
- Early Earth's atmosphere likely contained gases such as NH3, H2S, CO, CO2, CH4, N2, H2, and H2O.
- Biomolecules are complex organic substances essential for growth and maintenance of living organisms, derived from simple organic molecules like hydrocarbons.
Levels of Biological Organization
- Cells collaborating for a specific function form tissues.
- Tissues working together create organs.
- Groups of organs that perform related functions comprise biological systems, such as the circulatory system.
- Plant cells also group into tissues and organs, such as bark, roots, and leaves.
Prokaryotic vs Eukaryotic Cells
- Prokaryotes, including bacteria, lack a nucleus and membrane-bound organelles.
- Key features of prokaryotic cells:
- Cell wall
- Plasma membrane
- Genetic material organized in a nucleoid region
- Cytoplasm
- Ribosomes
