BCH 2333 TEST 1 Questions and Correct
Answers
What is biochemistry
-is the study of the chemistry of life
what was the goal of the miller urey experiment
-The purpose was to test the idea that the complex molecules of life (in this case, amino acids)
could have arisen on our young planet (even if the atmosphere was very reduced, so deprived of
O2) through simple, natural chemical reactions. The experiment was a success in that amino
acids, the building blocks of life, were produced during the simulation.
How did they do this
-they mimmicked condition of the old eart, with the ancient ocean and the atmosphere
-thing to not that the atmosphere was reduced (no O2)
-they heated it up and provided and energy source (lightening was the guess) to enable certain
reactions to occur
-they found from samples that building blocks were formed
How was this experiment further validified
-in 1969 metoeriote srtuck down
-the surface of it was very similar to the building blocks of life isolated in the experiment
-primordial earth was enoug to create this building life
what building blocks was to be fomed
what is chemical evolution
, -the formation of complex organic molecules from simpler inorganic building blocsk
How does molecular complexity arises? 1
-the formation of large biolgoical molecules (polymers) from inidividula units (momomers)
How does molecular complexity arise? 2
-the diversity of the available monomers capable of polymerization gives rise to chemical
versatility in the resulting macromolecule -so we have to have different times of monoemrs to
form different types of macromolecules
how can the complexity of the associaiton of individual polymers be sustained
-through complementarity
why is complmetnarity important?
-key to biopolymer self-replication,sustaining biochemical complexity
-this process is driven by natural selection
How is comparmentation created
-through biomolecular self assembly
self assembly= rearrerangmeent of position in space to form reproducible structures that
have a specific function (thermodynamically driven0
what drives the orgnization of cells/
-self assembly and compartmentation
through what process do supramolecular structures arise from
