Study Notes
Training Questions for Lectures 3, 4, and 5
- Scientific Term Definitions:
- Photosynthesis: A series of processes where light energy is converted to chemical energy in the form of a simple sugar.
- Carbon Dioxide Fixation: Carbon dioxide is fixed into simple sugars within chloroplasts.
- Nitrogen Fixation: Converting atmospheric nitrogen (N2) to ammonia. This ammonia is then metabolized by most organisms.
- Net Movement: Substance moves from high concentration areas to low concentration areas.
- Active Transport: Energy is used to transport molecules against their concentration gradient (low to high).
- Water Movement Through Membranes: Water moves from high water concentration areas to low water concentration areas across semi-permeable membranes
- Plant Tropisms: Directional plant movements in response to various stimuli. Includes gravity, light, water, and touch.
- Phytochemistry: Study of drugs from natural sources (plants, animals, and marine organisms).
- Crude Drug: Unrefined natural substance used medicinally for properties it intrinsically possesses.
- Pharmacopeia: Recognized book listing standards for drugs.
- Drug Recognition: Drugs may be recognized or not recognized by a pharmacopeia.
- Drug Adulterants: Inferior material added to drugs.
Additional Concepts
- Factors Affecting Photosynthesis & Diffusion: Photosynthesis and diffusion of molecules are affected by factors including a variety of elements.
- Natural Products in Medicine: Natural products are used in modern medicine because they contain molecules that can be used to create drugs that successfully treated or alleviated various medical conditions.
- Crude Drug Drying: Procedures, objectives, advantages, and considerations of drying crude drugs are important considerations.
- Drug Packaging: Good packaging of medicinal plants and how factors like packaging can factor in.
- Starch & Fixed Oil Uses: Explains various uses of starch and fixed oils.
- Photosynthesis Processes: The details of photochemical reactions, locations (grana vs. stroma).
- Limiting Factors of Photosynthesis: Explains which factors may limit photosynthesis.
- Water & Mineral Transport: How water and minerals are transported in plants (phloem/xylem).
- Cell Transport: Descriptions of active and passive transport (diffusion, facilitated diffusion, active transport) within cells.
- Types of Adulteration: Explains different types of adulteration in drugs.
- Antidotes of Poisoning and the components that might factor in
True/False and Multiple Choice
- Photosynthesis Location: Photosynthesis occurs in chloroplasts.
- Photosynthesis Compounds: Starch is high-energy storage in plants..
- Photosynthetic Pigments: Plant cell components includes components like calcium oxalate crystals as ergastic substances.
- Photosynthesis Reactions: Dark reactions take place in the grana (stroma, not grana).
- Photochemical Reactions: Photolysis of water and reduction of CO2 to glucose are considered photochemical reactions.
