Chapter 19, Problem 17P

Understanding the Oxidation of Glucose and Its Products in the TCA Cycle Glycolysis, the pyruvate dehydrogenase reaction, and the TCA cycle result in complete oxidation of a molecule of glucose to CO2. Review the calculation of oxidation numbers for individual atoms in any molecule, and then calculate the oxidation numbers of the carbons of glucose, pyruvate, the acetyl carbons of acetyl-CoA. and the metabolites of the TCA cycle to convince yourself that complete

oxidation of glucose involves removal of 24 electrons and that each acetyl-CoA through the TCA cycle gives up 8 electrons.

Biochemistry Question. Please help solve. Thank you! Based upon knowledge of oxidation of bioorganic compounds and howmuch energy is released during their oxidation, rank the following, from most to least, with respect to how much energy would be produced from each during their oxidation. Explain your placement for each one.
Biochemistry Question.For the metabolism of amino acids what is the first step for theirbreakdown? Why is it necessary for this breakdown product to be transported to the liver? For the catabolism of the carbon backbone of these amino acids, there are 7 entry points into the “standard” metabolic pathways. List these 7 entry points and which amino acids are metabolized to these entry points. Please help. Thank you!
Biochemistry Question. Please help. Thank you.   You are studying pyruvate utilization in mammals for ATP production under aerobic conditions and have synthesized pyruvate with Carbon #1 labelled with radioactive C14.   After only one complete cycle of the TCA cycle, which of the TCA cycle intermediates would be labeled with C14? Explain your answer.   Interestingly, you find C14 being excreted in the urine. How does it get there?
