Study Notes
Hormones and Endocrine System
- Hypothalamus regulates hunger, sleep, thirst, temperature, water balance, and blood pressure.
- Anterior pituitary removal minimally affects insulin levels.
- Thyroxine deficiency leads to symptoms like goiter and decreased metabolic rate.
- Glucagon is a hormone that directly impacts blood sugar levels.
Genetics and Inheritance
- Red-green color blindness is a sex-linked recessive trait; probability of a carrier woman passing it to a son is 1/2.
- Kleinfelter's Syndrome (XXY) is caused by nondisjunction.
- Sex-linked lethal recessive traits mainly cause death in males.
Cell Biology and Physiology
- Ribosomes are crucial for protein synthesis in eukaryotic cells.
- Exocytosis is the process by which large molecules exit cells.
- Cardiac muscle can contract independently of nervous stimulation.
Metabolism and Energy
- Insulin overdose can cause convulsions due to lowering blood glucose levels.
- Aldosterone counters fluid loss in nephrotic syndrome.
- Glucose serves as the primary energy source during the absorptive state.
Structure and Function
- The H-zone decreases in size during muscle contraction.
- Phagocytosis is the process where a cell engulfs large particles.
- Tight junctions in kidney epithelial cells prevent water permeability without ADH.
Evolution and Ecology
- Divergent evolution occurs when environmental factors separate a population into different adaptive paths.
- Denitrifying bacteria convert nitrates into nitrogen gas (N2).
Chemistry and Biochemistry
- Phosphoric acid titration involves phosphate ions at the third equivalence point.
- Disulfide bonds and peptide bonds are common in peptides.
- NaCl exhibits the strongest electrostatic interactions among given compounds.
Microbiology and Immunology
- Lysosomes and Golgi apparatus are responsible for protein processing in blood and urine.
- Transformation is the uptake of genetic material from the environment by bacteria.
Anatomy and Physiology
- Blood platelets are crucial for clot formation.
- The medulla oblongata controls the breathing rate.
- The mitral valve stenosis leads to elevated blood pressure in the left atrium.
Psychological and Neurological
- ACh binding in muscle cells leads to the release of Ca2+ from the sarcoplasmic reticulum.
- High blood pH (7.6) results in decreased CO2 exhalation.
Miscellaneous
- IR spectroscopy detects different functional groups in molecules.
- The boiling point is when a liquid's vapor pressure equals atmospheric pressure.
- Helminths are a category of organisms known as parasites.
Additional Key Concepts
- Medium-chain saturated fatty acids can be produced by altering thioesterase specificity.
- Enhanced membrane fluidity occurs when saturated fatty acids are replaced by unsaturated ones.
- Elevated fluid pressure in extracellular spaces results from lymphatic obstruction due to tumors.
