Study Notes
Flu Vaccines
- Flu vaccines train the immune system to recognize and fight the flu virus.
- They contain either inactivated (dead) or weakened live viruses.
- The nasal spray vaccine uses a weakened live virus.
- Egg-free vaccines use proteins from the flu virus.
- Flu vaccines are recommended for people 6 months and older.
- It takes about two weeks for the vaccine to become fully effective.
- Flu vaccines are updated annually to address new virus strains.
Metabolism & Cellular Processes
- Macronutrients, such as oxygen, are essential for cellular processes.
- Micronutrients, like zinc, are also necessary, but in smaller amounts.
- ATP is the cell's energy currency, powering various reactions.
- Enzymes catalyze (speed up) chemical reactions.
- Anabolism builds larger molecules from smaller ones; catabolism breaks them down.
- Mitochondria are the "powerhouses" of the cell, generating ATP through cellular respiration.
- Active transport moves molecules against their concentration gradient, requiring energy.
- Passive transport (simple and facilitated diffusion, osmosis) doesn't require energy.
- Osmosis is the movement of water across a membrane to equalize solute concentrations.
- Facilitated diffusion uses protein channels to move molecules across membranes.
Microbiology & Bacterial Growth
- Bacteria reproduce through binary fission.
- Aerobic respiration requires oxygen; anaerobic respiration does not.
- Aerobic respiration produces water and carbon dioxide as byproducts.
- Glycolysis breaks down glucose into pyruvate, a starting point for both aerobic and anaerobic respiration.
- Fermentation allows glycolysis to continue in the absence of oxygen, producing lactic acid (e.g., in muscles).
- Bacterial growth phases: lag (adjustment), log (exponential growth), stationary (growth equals death), death (death rate exceeds growth).
- Herd immunity protects a population by vaccinating a significant portion to reduce disease transmission.
Flu Vaccines
- Flu vaccines prepare the body to fight the flu without causing illness.
- Vaccines contain either dead or weakened flu viruses.
- The flu shot is administered via injection and contains dead or inactivated flu virus.
- The nasal spray flu vaccine contains a weakened but alive virus.
- The egg-free flu vaccine is made using proteins from the flu virus.
- Flu vaccines help the immune system recognize and fight off the flu virus.
- The flu shot typically takes two weeks to become effective.
- Flu vaccines are produced using flu viruses grown in eggs.
Metabolism
- Metabolism is the sum of all chemical reactions that occur within a living organism.
- Macronutrients are essential nutrients required in large amounts by cells, including oxygen, carbon, hydrogen.
- Micronutrients are essential nutrients required in smaller amounts, including zinc, iron.
- ATP is the cell's energy currency.
- Enzymes are biological catalysts that speed up chemical reactions.
- Active transport requires energy from the cell to move substances across a membrane against their concentration gradient.
- Passive transport does not require energy, including simple diffusion, facilitated diffusion, and osmosis.
- Osmosis is the movement of water across a selectively permeable membrane from a region of high water concentration to a region of low water concentration.
Respiration
- Respiration is the process of breaking down glucose to release energy.
- Aerobic respiration requires oxygen and produces the most ATP (water and carbon dioxide).
- Anaerobic respiration does not require oxygen (fermentation produces lactic acid).
- Glycolysis is the first step in cellular respiration, breaking down glucose to pyruvate.
- Krebs cycle is a metabolic pathway that occurs in the mitochondria.
- Electron transport chain is the final stage of aerobic respiration.
- NADH and FADH2 are electron carriers.
Bacterial Growth
- Bacteria reproduce by binary fission.
- Lag phase: Bacteria are adjusting to their environment, no cell division.
- Log phase: Bacteria reproduce rapidly, exponential growth.
- Stationary phase: The rate of new cell formation equals the rate of cell death.
- Death phase: The rate of cell death exceeds the rate of new cell formation.
Cell Transport
- Endocytosis is the process by which cells engulf substances to bring them into the cell.
- Exocytosis is the process by which cells expel substances from the cell.
Herd Immunity
- Herd immunity is the indirect protection of unvaccinated individuals when a large proportion of the population is immune.
