Study Notes
Triacylglycerols and Energy Storage
- Triacylglycerols are not highly hydrated, enhancing energy density.
- Fatty acid chains yield more energy upon oxidation due to high reduction.
- They vary in length and saturation, affecting energy release.
Resistance in Electrical Wires
- Resistance increases with wire length and decreases with cross-sectional area.
- Longer wires increase resistance; wider wires decrease resistance.
- Lowering temperature reduces resistivity, leading to better conductivity.
Sexual Reproduction Advantages
- Sexual reproduction results in genetic recombination, fostering diversity.
- Each fertilization combines unique genetic material from two parents.
- This enhances phenotypic variability in populations.
Composition of Pus
- Pus primarily contains phagocytosed bacterial remnants.
- Microscopic samples of pus reveal granulocytes, monocytes, and macrophages.
- Neutrophils are critical in the non-specific immune response to pathogens.
Cholesterol Functionality
- Cholesterol serves as a precursor for steroid hormones.
- It can both increase and decrease membrane fluidity depending on temperature.
- Cholesterol interacts with both hydrophobic and hydrophilic components of phospholipids.
Osteogenesis Imperfecta and Genetic Probability
- Osteogenesis imperfecta is an autosomal dominant condition.
- The probability of an affected man’s sister having the disease relies on the father's genotype.
- The mother's genotype does not influence the sister's risk since she is unaffected.
