BMSC 200 REVIEW WITH CORRECT
SOLUTIONS!!
What are the four "foundations of life"? - ANSWERChemical, energy, genetic and
evolutionary
What are the four chemical foundations? - ANSWERHydrogen, oxygen, carbon and
nitrogen
Why is carbon better than silicon? - ANSWERCarbon-carbon bonds are stronger and
release more energy when they combust
Conformation - ANSWERFlexible spatial arrangement of atoms within a molecule.
Can be changed without breaking the covalent bonds
Configuration - ANSWERFixed spatial arrangement of atoms within a molecule.
Can't change without breaking covalent bonds
Geometric Isomers - ANSWERHave the same chemical formula but differ in the
configuration of groups with respect to a non-rotating double bond
G<0 - ANSWERSpontaneous, releases free energy which can be used to do work,
proceeds until equilibrium is reached. Exergonic
G=0 - ANSWERSystem a equilibrium, no change in free energy in the system
Perpetuation of life requires that genetic information be: - ANSWERsorted in a stable
form, expressed accurately in the form of gene products and reproduced with
minimal error
DNA provides: - ANSWERinstructions for forming all other cellular components and
a template for production of identical DNA molecules to be distributed
Cis - ANSWEROn the same side of the double bond
Trans - ANSWEROn the opposite sides of the double bond
Chiral Carbons - ANSWERHas four different substituent attached to it
Construction - ANSWERBiomolecules often constructed exclusively from one
stereoisomer
Interactions - ANSWERInteractions between biomolecules, as well as between
biomolecules and small molecules, are stereospecific
