⩥ Jacques Monod Quote. Answer: "Anything true of E. coli must be true
of elephants." — emphasizes biochemical unity.
⩥ Four Foundations of Life. Answer: Chemical, Energy, Genetic,
Evolutionary.
⩥ Elements making up most living organisms. Answer: Carbon,
Hydrogen, Oxygen, Nitrogen (~98%).
⩥ Why water is important for life. Answer: Provides much of the
hydrogen and oxygen in organisms.
⩥ Why life is carbon-based. Answer: Carbon forms many stable
covalent bonds allowing complex molecules.
, ⩥ Why carbon is better than silicon for life. Answer: Carbon-carbon
bonds are stronger, release more energy, and produce recyclable CO₂.
⩥ Nitrogen availability. Answer: Nitrogen gas (N₂) in air is inert; plants
obtain usable nitrogen from soil.

today).
⩥ Estimated value of tissues/organs/biomolecules in body. Answer:
~$45 million.
⩥ Functional groups. Answer: Groups of atoms that determine the
chemical properties and reactions of biomolecules.
⩥ Properties functional groups affect. Answer: Size, shape, charge,
reactivity, hydrogen bonding ability.
⩥ Protonation states of functional groups. Answer: Functional groups
can exist in different forms depending on protonation (e.g., COO⁻ vs
COOH).
