BCH 2333 TEST 1 Exams Questions and Answers

BCH 2333 TEST 1 What is biochemistry - Answer- -is the study of the chemistry of life what was the goal of the miller urey experiment - Answer- -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 - Answer- -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 - Answer- -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 - Answer- what is chemical evolution - Answer- -the formation of complex organic molecules from simpler inorganic building blocsk How does molecular complexity arises? 1 - Answer- -the formation of large biolgoical molecules (polymers) from inidividula units (momomers) How does molecular complexity arise? 2 - Answer- -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 - Answer- -through complementarity why is complmetnarity important? - Answer- -key to biopolymer self-replication,sustaining biochemical complexity -this process is driven by natural selection How is comparmentation created - Answer- -through biomolecular self assembly self assembly= rearrerangmeent of position in space to form reproducible structures that have a specific function (thermodynamically driven0 - Answer- what drives the orgnization of cells/ - Answer- -self assembly and compartmentation through what process do supramolecular structures arise from - Answer- -from self assembly from polymers what defines the functionality of the polymer that they are incorporated into - A
