Question
Help Save & Exit You received partial credit in the previous attempt. 2 Consider the following metabolic scenarios, and determine whether they are catabolic (energy releasing) or anabolic (energy requiring) processes. anabolic anabolicCO, is fixed into glucose following six turns of the Calvin cyc Triglycerides are broken down into glycerol and fatty acids which enter glycolysis and the Krebs cycle. catabolic DNA polymerase catalyzes the formation of the phosphodiester catabolicbond between nucleotides during replication. Messenger RNA is translated into proteins in the ribosomes. anabolicMes Removal of the amino group in an amino acid converts it to a catabolic carbohydrate in a process called deamination
Explanation / Answer
Anabolic reactions describe the set of metabolic reactions that build up complex molecules from simpler ones.
Catabolic reactions describe the set of metabolic reactions that break complex molecules down into simpler molecules.
In the above figure,
process 1 - anabolic (synthesis of macromolecule Glu from CO2)
process 2 - catabolic (breaking down of triglycerides releases energy. Krebs cycle is catabolic.)
process 3 - anabolic (phosphodiester bond formation between nucleotides occurs during synthesis of nucleic acids)
process 4 - anabolic (this is again a constructive process where complex protein is formed from simpler mRNA)
process 5 - catabolic (deamination means removal of amine group which is a breakdown or catabolic process)
process 6 - anabolic (peptidoglycan polymer is synthesized from NAM-NAG monomers)
