(a) Interpretation: In terms of protein synthesis, the representation of 100S and 130S particles should be determined. Concept Introduction: Ribosome is defined as a minute particle that comprises of ribonucleic acid (RNA) and the proteins associated to it are found in the cytoplasm of living cells.

Arrange the four structures in order from most reduced to most oxidized. Most reduced R-CH2-CH3 R-CH2-CH₂-OH R-CH,-CHO R-CH₂-COO Most oxidized

for each pair of biomolecules, identify the type of reaction (oxidation-reduction, hydrolysis, isomerization, group transfer, or nternal rearrangement) required to convert the first molecule to the second. In each case, indicate the general type of enzyme and cofactor(s) c reactants required, and any other products that would result.
