(a)

Summary Introduction

To determine: Whether the given metabolic reaction is oxidation or reduction.

Introduction:

The metabolic processes taking place in the cells are the continuous series of oxidation and reduction. The oxidation and reduction processes results in the production of ATP. Oxidation occurs due to hydrogenation of the compound andinvolves addition of one oxygen atom. Reduction refers to the removal of oxygen atom from the substance.

Biochemistry What is the process of "transamination" in either the muscles or the liver, that involves keto acid or glutamic acid? Please explain how the steps work. Thank you!
Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
Biochemistry Please help. Thank you When carbamyl phosphate is joined to L-ornathine, where does the energy for the reaction come from?
