Question
Chapter 25.3, Problem 25.5P
Interpretation Introduction
Interpretation:
In which type conversion of alanine to pyruvic acid should be identified via oxidation reaction.
Concept Introduction:
Amino acids: Compound that contains an amino group, a carboxyl group a side chain that is specific to each amino acid.
Several type of amino acids the amino group is on the carbon adjacent to the carbonyl group.
They are molecules containing an amino group a carboxyl group a
Amino acid oxidation: Amino acids undergo oxidative catabolism under three conditions.
- Proton amino acid residues from normal turnover are recycled to generated energy and molecular compounds.
- Dietary amino that exceed body’s protein synthesis needs are degraded.
- Proteins in the body are broken down to supply amino acid for catabolism when carbohydrate is in short supply.

- In 1937, two German biochemists published a paper proposing these reactions as part of glucose oxidation: citrate → isocitrate → α-ketoglutarate →succinate → fumarate → malate → oxaloacetate. Adding succinate, fumarate, or malate to thin slices of tissue increased oxygen consumption, supporting the hypothesis that these molecules are intermediates in the process. However, they were puzzled by the observation that these intermediates were still present in the reaction mixture at the end of the experiment. They had thought that intermediates would be consumed as they were converted to the next molecule in the pathway. What explains the observation that these intermediates were still present? a) The pathway is a cycle, constantly regenerating intermediates as glucose is broken down. b) Succinate, fumarate, and malate are not reactants but catalysts, and catalysts are not consumed in the process. c) Succinate, fumarate, and malate increase metabolism and therefore oxygen consumption,…arrow_forwardUsing the Krebs cycle explain oxidative decarboxylation.arrow_forwardWhat are the possivble oxidation product of catalase using H2O2 as the substrate?
