BMSC 200 QUIZ 1 WITH COMPLETE
SOLUTIONS
4 biomolecules - Correct Answers -carbohydrates, lipids, proteins, nucleic acids
conformation - Correct Answers -flexible spatial arrangement of atoms within a molecule
(can be changed without breaking covalent bonds).
configuration - Correct Answers -fixed spatial arrangement of atoms within a molecule
(cannot be changed without breaking covalent bonds)
- double bonds + chiral centers
biochemistry - Correct Answers -- 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 - Correct Answers -Four elements that account for 98% of most organisms.
C (plants), O (air), H (water) - Correct Answers -elements readily available in biosphere
Nitrogen - Correct Answers -Plants extract _ from soil, and when we eat them, we get
the source
Fritz Haber - Correct Answers -German Chemist. He won the 1918 Nobel Prize in
chemistry for the development of the process used for synthesizing ammonia from its
elements.
silicon - Correct Answers -next 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 - Correct Answers -- 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).
- Combustion products of carbon (carbon dioxide) are soluble and remain active in
biosphere (recycling).
ketone - Correct Answers -carbon double bonded to oxygen
aldehyde - Correct Answers -CHO
hydroxyl - Correct Answers -OH-
