The synthesis of products is limited by the amount of reactants.(a) If one mole each of CH4, NH3, H2S, and CO2 is added to 1 literof water (= 55.5 moles of H2O) in a flask, how many moles ofhydrogen, carbon, oxygen, nitrogen, and sulfur are in the flask?(b) Looking at the molecular formula in the table, how manymoles of each element would be needed to make 1.0 mole ofglycine? (c) What is the maximum number of moles of glycine thatcould be made in that flask, with the specified ingredients, if noother molecules were made? Explain. (d) If serine or methioninewere made individually, which element(s) would be used up firstfor each? How much of each product could be made?
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
The synthesis of products is limited by the amount of reactants.
(a) If one mole each of CH4, NH3, H2S, and CO2 is added to 1 liter
of water (= 55.5 moles of H2O) in a flask, how many moles of
hydrogen, carbon, oxygen, nitrogen, and sulfur are in the flask?
(b) Looking at the molecular formula in the table, how many
moles of each element would be needed to make 1.0 mole of
glycine? (c) What is the maximum number of moles of glycine that
could be made in that flask, with the specified ingredients, if no
other molecules were made? Explain. (d) If serine or methionine
were made individually, which element(s) would be used up first
for each? How much of each product could be made?
