Questions and Answers

What are the 4 main molecules that make up 98% of us?

  • Hydrogen, carbon, oxygen, nitrogen
  • Carbon, nitrogen, oxygen, silicon
  • Oxygen, nitrogen, carbon, silicon
  • Hydrogen, oxygen, nitrogen, carbon (correct)

    • Why can't we directly take nitrogen from the air?

  • It is in the form of N2, which is toxic (correct)
  • It is highly reactive in its natural state
  • It is present in very low concentrations in the air
  • It is bound to other elements making it inaccessible

    • What is the advantage of carbon over silicon?

  • Carbon dioxide produced from carbon combustion is insoluble
  • Silicon is less abundant than carbon
  • C-C bonds are stronger and release more energy on combustion (correct)
  • Silicon can only make 2 covalent bonds

    Study Notes

    Module 1 Chapter 1 Objectives

    • Compare and contrast prokaryotes and eukaryotes to understand their basic differences and similarities

    Chemical Foundations of Life

    • Identify chemical functional groups that are essential for life
    • Recognize and discriminate different types of chemical functional groups

    Stereochemistry in Biochemistry

    • Identify chiral carbons and explain their importance in biochemistry
    • Understand how stereochemistry relates to biochemistry and its significance

    Biomolecules

    • Describe the four major classes of biomolecules: nucleic acids, proteins, polysaccharides, and lipids
    • Identify the unique building blocks and linkages within each class of biomolecules

    Thermodynamic Perspective of Life

    • Describe life from a thermodynamic perspective, understanding the energy transformations that occur

    Genetic Basis of Living Organisms

    • Summarize the genetic basis of living organisms, considering its relation to evolution
    • Recognize the unity of biochemistry, where all building blocks are equal in all living things

    Biochemistry and Interconnectedness

    • Understand that biomolecules can be transferred and transformed between organisms, illustrating the interconnectedness of life (e.g., eating a banana, being eaten by a shark)
