From the Exam 1 Study Guide:
What are the main elements used by living organisms?
- What are the rationales for life depending on H, O, N, &
- Why add S & P?
- Why should life be mainly a phenomena of the 2nd and
3rd electron shells? (Think about this but don't spend too much
time on it on my account!)
- How about the elements occurring mainly as ions ?
- Na, K, Ca, Cl, etc.
- Fe, Zn, Cu etc.
What are the main families of biomolecules and what are their
characteristic functional groups and/or functions? Note the small
molecules (inorganic molecules and molecular ions, monomers and
metabolites) vs. large molecules (polymers):
- inorganics ("mineral")
- amino acids/proteins
- nitrogenous bases (nucleotides)/nucleic acids
