Study Notes
Unit 1 Review: Chapters 1-5
- Chapter 1: Focuses on microbiology history, categorizing microbes (bacteria, archaea, protozoa, fungi) and their roles. Includes key figures, microbial definitions (mycology, bacteriology), bioremediation, infectious diseases, and biofilms.
Chapter 2
- Atoms and Molecules: Discusses atomic structures, bonding types (covalent, polar, nonpolar, and noncovalent), acids/bases (pH), and the significance of carbon.
- Macromolecules: Covers the structure, function, and monomers of macromolecules.
Chapter 3
- Microscopy: Explores light microscopy, its parts, functions, and different types like simple vs. differential staining.
- Staining Techniques: Focuses on gram-staining, acid-fast stain, negative, endospore, and flagella staining techniques.
Chapter 4
- Prokaryotic Cell Structure: Details bacterial shapes, arrangements, and external structures.
- Cellular Components: Emphasizes cell wall structures, plasma membranes, their properties, transportation mechanisms, inclusions, and endospores (with regards to bacteria).
- Eukaryotic Cells: Briefly touches upon eukaryotic cell organelles.
Chapter 5
- Enzymes and Their Inhibition: Covers enzyme inhibition (competitive, allosteric, feedback).
- ATP Production: Defines 3 ways cells make ATP (e.g. respiration).
- Respiration, Fermentation, and Biochemical Tests: Explores the metabolic processes of respiration (in detail) and its steps for energy production, fermentation alternatives, as well as biochemical tests.
- Photosynthesis: Explores photosynthesis, its stages (light and dark reactions), and the Calvin cycle.
- Types of Metabolic Feeding: Discusses different types of metabolic feeding (photoautotrophs, chemoheterotrophs, etc.).
