BMSC 200 QUIZ 1CORRECT 100%
4 biomolecules - ANSWERcarbohydrates, lipids, proteins, nucleic acids
conformation - ANSWERflexible spatial arrangement of atoms within a molecule (can
be changed without breaking covalent bonds).
configuration - ANSWERfixed spatial arrangement of atoms within a molecule
(cannot be changed without breaking covalent bonds)
- double bonds + chiral centers
biochemistry - ANSWER- the study of life at the molecular level.
- the application of the principles of chemistry to
explain biology.
- the common sets of reactions and principles that underlie all living organisms.
- the study of the molecular logic of life.
C, H, O, N - ANSWERFour elements that account for 98% of most organisms.
C (plants), O (air), H (water) - ANSWERelements readily available in biosphere
Nitrogen - ANSWERPlants extract _ from soil, and when we eat them, we get the
source
function - ANSWERFor all biomolecules, structure dictates
isomers - ANSWERSame atoms but different arrangement.
cis (isomners) - ANSWERgroups on the same side of the double bond
trans (isomers) - ANSWERgroups on opposite sides of the double bond
chiral carbon - ANSWERCarbon atom with four different groups attached
Fritz Haber - ANSWERGerman Chemist. He won the 1918 Nobel Prize in chemistry
for the development of the process used for synthesizing ammonia from its
elements.
silicon - ANSWERnext best candidate as chemical foundation bc it can form 4
covalent bonds and is highly abundant in Earth's crust
carbon is better than silicon - ANSWER- Carbon-to-carbon bonds are stronger than
silicon-to-silicon bonds (more stable biomolecules).
- More energy released on combustion of carbon-carbon bonds (more energy from
carbon-based nutrients).
