Study Notes

Animal Systems

Positive feedback loop examples: Childbirth (oxytocin release), blood clotting (platelet activation), fruit ripening (ethylene production).
Negative feedback loop examples: Body temperature regulation (sweating or shivering), blood sugar regulation (insulin and glucagon), blood pressure regulation (baroreceptors and heart rate adjustment).
Respiratory System & Homeostasis during exercise: Increased breathing rate and depth provide more oxygen to the muscles, and remove carbon dioxide faster. This helps maintain blood pH balance.
Circulatory system importance: Delivers oxygen and nutrients to tissues, removes waste products, and regulates body temperature.
Liver & Urea Production: The liver works with the excretory system to produce urea.
Digestive tract disruptions: Malfunctions in the digestive tract can lead to issues like indigestion, malabsorption of nutrients, and bowel problems.
Parasites & Body systems: Parasites can affect multiple body systems, causing symptoms like anemia (blood), diarrhea (digestive), skin rashes (integumentary), and fatigue (nervous).
Childbirth Systems: Reproductive, muscular, nervous, and circulatory systems are all involved in childbirth.
Hormone Release Diagram: Hormones are released from glands and travel through the bloodstream to target cells with specific receptors.
Respiratory system gas exchange: Oxygen is absorbed from the air into the blood and transported to cells. Carbon dioxide is released from cells into the blood and exhaled.
Systems for blood glucose regulation: Endocrine (pancreas releases insulin and glucagon), digestive (absorbs glucose from food), circulatory (transports glucose).
Systems involved in defending against viruses: Immune (antibodies and white blood cells), lymphatic (transports immune cells), circulatory (transports immune cells and antibodies).

Plant Systems

Waxy cuticle function: Protects the plant from excessive water loss.
Vascular plant survival on land: The vascular system, composed of xylem (water transport) and phloem (food transport), allows plants to transport essential materials throughout their bodies.
Water and mineral absorption: Roots absorb water and minerals from the soil using root hairs.
Stomata opening and closing: Stomata open when the plant needs to take in carbon dioxide for photosynthesis and close to conserve water. They open in the presence of light and close in darkness.
Plant tropisms: Phototropism (growth towards light), gravitropism (growth in response to gravity), thigmotropism (growth in response to touch).
Water retention during drought: Plants can minimize water loss by closing their stomata, shedding leaves, and developing deep root systems.
Fern vs. Mosses: Ferns have vascular tissue and can grow taller than mosses, which lack vascular tissue and are limited to moist environments.
Stomata location: Stomata are typically located on the underside of the leaf, minimizing water loss.
Flower parts and functions: Petals (attract pollinators), sepals (protect bud), stamen (produces pollen), pistil (contains egg).
Plant phyla: Bryophytes (mosses, liverworts), Pteridophytes (ferns), Gymnosperms (conifers), Angiosperms (flowering plants).

Cellular Energetics

Oxygen source in photosynthesis: Oxygen comes from the splitting of water molecules during the light-dependent reactions.
Light-dependent vs. light-independent reactions: Light-dependent reactions capture light energy and convert it to chemical energy (ATP and NADPH). Light-independent reactions use ATP and NADPH to fix carbon dioxide into sugar.
ATP/ADP bond storage and release: Energy is stored in the bonds between phosphate groups in ATP. Energy is released when a phosphate group is removed, converting ATP to ADP.
Cellular respiration functions: Breakdown of glucose to produce ATP (energy). Includes glycolysis, Krebs cycle, and electron transport chain.
Lactic acid fermentation: Occurs when oxygen is limited, converting pyruvate to lactic acid and producing a small amount of ATP.
Gizmo activity: Gas bubbles (oxygen) are produced by photosynthesis. The color of the solution is an indicator of photosynthesis efficiency.
Light and photosynthesis correlation: Photosynthesis increases with increasing light intensity up to a certain point.
ATP production process: Cellular respiration is the primary process involved in ATP production.
Photosynthesis and cellular respiration equations:
Photosynthesis: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
Cellular Respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
Diagrams: Draw diagrams for both processes, including the key molecules and steps involved.
