Organic Compounds


  • Protein
    • Most abundant organic compound
    • Fundamental structural and functional frameworks of the cell’s protoplasm
    • Kinds:
      • Structural/Fibrous protein – build and repair body cell tissues
    • Globular/Enzymatic protein – biological catalyst in almost every chemical reaction
  • Nucleic acid
    • DNA and RNA
  • Carbohydrates
    • Chief energy source
    • Backbone of molecules
    • When combined with protein, they form glycoproteins and proteoglycans
    • Classifications:
      • Monosaccharide – simple sugar which serves as building blocks for more complex forms like glucose, fructose, galactose
      • Disaccharides – formed by chemical combination of 2 monosaccharides but with removal of water molecules (like maltose, sucrose, lactose)
      • Polysaccharide – series of monosaccharides
        • Starch – serves as units of glucose
        • Glycogen – stored carbohydrates found in animals
        • Cellulose – insoluble carbohydrate; abundant in the tough outer wall of plant cells
        • Chitin – exoskeleton of animals
  • Lipids
    • Fats and oils
    • Served as the highest source of energy
    • Acts as insulator protecting animals from extreme cold
    • Contributes to the cell membrane semi-permeability(as phospholipids)
    • Building blocks for many steroids
    • Classifications:
      • Neutral – major fuels for animals; saturated (cholesterol); unsaturated
      • Phospholipids – biological component in the plasma membrane
      • Sphingolipids – maintain the right shape of organs and tissues
        • Waxes – example: polishers, ointments and lubricants
        • Steroid – complex units of alcohol
        • Cholesterol
        • Sex hormones
        • Bile salt (emulsifier of fats)

English: Subject and Verb Agreement

-
Image
Basic Rule: A singular subject takes a singular verb, while a plural subject takes a plural verb. Example: She dances gracefully. (singular) They dance together. (plural) Rule 1: Two singular subjects connected by "or" or "nor" require a singular verb. Example: Mom or dad is arriving at 10 in the morning. Rule 2: Two singular subjects connected by "either/or" or "neither/nor" require a singular verb. Example: Neither Tina nor Anne is available. Either Tom or Dan is working today. Rule 3: If "I" is one of the two subjects connected by either/or or neither/nor, put it second and follow it with the singular verb am. Example: Neither she nor I am going to the party. Rule 4: If a singular subject is connected by "or" or "nor" to a plural subject,place the plural subject last and use a plural verb. Example: The cook book or the fiction novels go on that shelf. - - - - - - - - - - - - - ...

Ethnocentrism practice of judging all other cultures by one's own culture based on assumption that one's way of life is superior to all others forms of ethnocentrism            - positive ethnocentrism: school songs, national anthem, pledge to flags/patriotism           - negative ethnocentrism: customs, dress, eating habits, religious beliefs is marked differently from those of dominant group members 2. Cultural Relativism inverse/opposite of Ethnocentrism practice of judging other cultures by his own context 3. Xenocentrism preference the products, styles, ideas, or ideas of someone else's culture rather than of one's own (colonial mentality); Xeno means foreign 4. Cultural Shock when you are confronted with other culture, there is a feeling of anxiety and disorientation 5. Cultural Lag maladaptation maladjustment there is rapid improvement whe...
