Only the most inspirational study of organisms out there *:)
question | answer |
---|---|
the study of carbon compounds is called what? | organic chemistry |
how do carbon atoms form diverse molecules? | by bonding to atlwast four other atoms |
a small group of chemical groups is key to what? | functioning of biological molecules |
carbon is what in relation to life? | the backbone |
plants use solar energy to transform CO2 and form what? | molecules of life |
carbon is unparalleled in it's ability to form what types of molecules? | large, complex, and diverse ones |
what has made possible the diversity of organisms? | the diversity of carbon |
Proteins, DNA, carbohydrates, and other molecules are bonded in what ways? | to each other and to atoms of other elements |
other "living" matter compounds consist of what 5 compounds other than carbon? | hydrogen, oxygen, nitrogen, sulfur, and phosphorusc |
compounds containing carbon are called what? | organic |
most organic compounds tend to contain what in addition to carbon atoms? | hydrogen atoms |
what major elements of life in block form? | CHONSP |
different species/individuals of a species vary in what type of molecules? | organic molecules |
chemists made simple compounds in what time period? | the early 1800's |
Vitalism by Jakob is a belief that what is outside chemical and physical laws? | a life force |
inorganic salt an attempt in 1828 by Wohler trying to make inoragnic salt by mixing a solution of ammonia and cynate ions but ended up with what? | urea |
who made an organic compound from inorganic substance? | Hermmane Kolbe |
abiotic nonliving sythesis of living compounds a text written by Stanley miller in 1953 through his Miller experiments testing early earth conditions | a text written by Stanley miller in 1953 through his Miller experiments testing early earth conditions |
mechanism | physical and chemical laws govern all phenomenon |
the foundation of organic chemistry | is not some intangible life force, but the unique chemical versatility of the element carbon |
When Miller tried the experiment without electrical discharge, no organic compounds were found. | the spark could provides energy needed for inorganic molecules in the atmosphere to react with each other |
What if Miller increased the concentration of NH3 in his experiment, how might the relative amounts of the products HCN and CH2O have differed? | because the concentration of the reactants influences the equilibrium there might be more HCN relative to CH2O, since there would be higher concentrations of the reactant gas that causes hydrogen |
What conclusion can Stanley Miller draw when he found amino acids in his experiment? | Amino acids are essential for living organisms. Their synthesis from gases of primitive atmosphere on earth demonstrates that life's molecules could initially have been synthesized from non living molecules |
