Instructions: — Please answer properly — Donot copy here in Bartleby or in Google. QUESTION; — Compare and contrast the degradation pathways of purines and pyrimidines, making sure to mention whether bases get oxidized or reduced. Explain why pyrimidine nucleotide degradation contributes (to a limited extent) to the energy metabolism of the cell.
1. Requirements of Active Sites in Enzymes The active site of an enzyme usually consists of a pocket on the enzyme surface lined with amino acid side chains necessary to bind the substrate and catalyze its chemical transformation. Carboxypeptidase, which sequentially removes the carboxyl-terminal amino acid residues from its peptide substrates, consists of a síngle chain of 307 amino acids. The two essential catalytic groups in the active site are furnished by Arg45 and Glu²7º. (a) If the carboxpeptidase chain were a perfect a-helix, how far apart (in nanometers) would Arg'45 and Glu²7º be? Hint: In an æ-helix, there is 1.5 Å translation of the backbone per residue (Chapter 3). (b) Explain how it is that these two amino acids, so distantly separated in the sequence, can catalyze a reaction occurring in the space of a few tenths of a nanometer. (c) If only these two catalytic groups are involved in the mechanism of hydrolysis, why is it necessary for the enzyme to contain such a large…

[Ten - Biomolecules] INSTRUCTIONS — Answer the following multiple-choice questions and EXPLAIN in 3-5 sentences why you chose that answer. — Answer properly Questions; Thomas was purifying an enzyme from a homogenate of muscle cells. He went through seven steps of purification and found that the enzyme activity was the same as the homogenate value. On the eighth step, when the protein washighly pure, the enzyme activity rose to five times that of the homogenate value. Can you suggest a possible reason? A. the homogenate assay was wrong B. step eight has co-purified an activator of the enzyme. C. the enzyme has an inhibitor present in the muscle cell homogenate D. the temperature at step eight was just right for the enzyme activity.
