Study Notes
Cell Biology
- Cells have organelles with specific functions
- Nucleus: controls cell activity, contains DNA
- Cytoplasm: gel-like substance where reactions occur
- Ribosomes: protein synthesis
- Mitochondria: respiration, energy production
- Chloroplasts (plant cells): photosynthesis
- Cell wall (plant cells): provides support
- Cell membrane: controls what enters/exits the cell
- Specialized cells have adaptations for their roles
- Examples: nerve cells (transmit electrical signals), muscle cells (contract), red blood cells (carry oxygen), root hair cells (absorb water/minerals)
- Cell division
- Mitosis: cell division process with stages (prophase, metaphase, anaphase, telophase) crucial for growth, repair, and asexual reproduction.
- Cell cycle: Interphase, Mitosys, Cytokinesis, the cell cycle is the series of events that takes place in a cell leading to its duplication.
- Control of the cell cycle: regulates cell division.
Transport in Cells
- Diffusion: movement from high to low concentration, influenced by surface area, concentration gradient, and temperature.
- Osmosis: movement of water across a semipermeable membrane, based on water potential.
- Active transport: movement against a concentration gradient, requiring energy. Examples: mineral uptake by plant roots.
Organization
- Animal tissues:
- Epithelial: Covers surfaces, protection.
- Connective: Supports and connects tissues (e.g., blood, bone, cartilage).
- Muscle: Contracts for movement
- Nervous: Transmits electrical signals.
- Organs and organ systems:
- Examples: heart (circulatory system), lungs (respiratory system), stomach and intestines (digestive system), kidneys (excretory system).
- Interactions: Systems working together (e.g., circulatory and respiratory systems for oxygen transport).
Infection and Response
- Communicable diseases:
- Pathogens: Bacteria (Salmonella), viruses (measles), fungi (athlete's foot), protists (malaria).
- Transmission: Direct contact, air, water, vectors.
- Immune responses:
- White blood cells: Phagocytes (engulf pathogens), lymphocytes (produce antibodies).
- Antibodies: Proteins that bind to antigens.
- Antigens: Molecules on the surface of pathogens
- Vaccinations: Introduce weakened/inactive pathogen to stimulate antibody production.
- Herd immunity: Protection for a population when many individuals are immune.
Bioenergetics
- Photosynthesis:
- Equation: 6CO2 + 6H2O → C6H12O6 + 6O2
- Factors: Light intensity, CO2 concentration, temperature
- Respiration:
- Aerobic: Requires oxygen, produces ATP
- Anaerobic: Does not require oxygen, produces less ATP and lactic acid.
Chemistry
- Atomic structure and periodic table:
- Atomic structure: protons, neutrons, electrons, isotopes.
- Periodic table: groups and periods, trends in properties.
- Ionic and covalent bonding:
- Ionic: electrostatic attraction between ions
- Covalent: sharing electrons
- Energy changes:
- Exothermic (releases energy):ΔH is negative
- Endothermic (absorbs energy): ΔH is positive
Physics
- Energy:
- Energy stores: kinetic, gravitational potential, elastic potential, chemical, thermal
- Energy changes and transfers.
- Electricity:
- Current, potential difference, resistance, Ohm's Law (V = IR).
- Series and parallel circuits. Domestic circuits.
- Particle model of matter:
- Changes of state (melting, boiling, freezing, condensation, sublimation, deposition) relationship to particle movement.
Internal Energy
- Internal energy: Total kinetic and potential energy of particles in a substance
- Relationship to temperature: Internal energy increases as temperature increases
- Specific heat capacity: Q = mcΔT (where Q is energy transferred, m is mass, c is specific heat capacity, and ΔT is the change in temperature).
- Atomic structure and radioactivity
- Atoms and isotopes: isotopes, Radioactive decay: (alpha, beta, gamma), Half-life
- Nuclear radiation: Ionizing radiation, uses (medical tracers, radiotherapy), hazards (cell damage, cancer). Nuclear fission (splitting of atoms) and fusion (joining of atoms).
