Study Notes
Atomic Participation and Molecular Characteristics
- 6 CO2 + 6 H2O combines to form C6H12O6 + 6 O2, totaling 36 atoms in the reaction.
- Molecular formula C6H12O6 reveals kinds and numbers of atoms, molecular weight, and numerical proportion, but does not indicate atomic arrangement.
Carbon Atom Composition
- A carbon atom with 6 protons, 7 neutrons, and 6 electrons is classified as an isotope, not a cation, anion, or a metal.
Bicarbonate Functions in Blood
- Bicarbonate ions serve as buffers in human blood, helping to maintain stable pH levels.
pH and H+ Ion Concentration
- A solution with a pH of 2 contains 0.01 moles of H+ ions per liter.
- Rainwater with an H+ concentration of 10^-4 M has a pH of 4.
Water Movement in Trees
- Water's ability to adhere to surfaces, be an effective solvent, and have strong molecular attraction aids in its rapid movement through trees.
- Water concentration does not directly dictate movement.
Oxidation-Reduction Reactions
- All biological oxidation-reduction reactions involve the transfer of electrons.
Enzymatic Reactions in Red Blood Cells
- In the carbonic anhydrase reaction, the substrates include CO2 and H2O.
Acidity Scale
- A solution with a pH of 5 is 100 times more acidic than one with a pH of 7.
Structural Formulas
- Generalized structural formulas can represent monosaccharides, such as glucose.
Glycogen Hydrolysis
- Hydrolysis of glycogen yields glucose, the basic unit of glycogen.
Hormonal Structures
- Steroids are classified as hydrophobic hormones, typical examples of primary structure in this category.
Inorganic Nutrients
- Calcium functions as an inorganic nutrient essential for regulatory activities among various cell types.
Sugar in DNA
- DNA contains deoxyribose, a 5-carbon sugar, which is critical for its structure.
