Calculate the ATP yield for the complete oxidation of the ketone body 3-hydroxybutryate to 4 CO2 in the mitochondrial matrix. Use P:O ratios of 2.5 for NADH and 1.5 for QH2. Draw the chemical reaction and the movement of electrons (including the enolate intermediate) necessary for the spontaneous decarboxylation of acetoacetate to acetone and CO2. (Hint: review the mechanism of step 4 in glycolysis and step 3 in the citric acid cycle). Why is acetoacetate undergoing spontaneous decarboxylation while 3-hydroxybutyrate does not?
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.
