Explain the basis for the following statement: As a coenzyme, pyridoxal phosphate is covalently bound to enzymes with which it functions; yet during catalysis the coenzyme is not covalently bound.
Starting with glucose, there are five steps in the EMP/TCA metabolic pathways that produce NADH (which is
converted to ATP or energy). Use class notes, Shuler, Kargi and DeLisa book, or the internet.
1.
A. Draw the chemical structures of the reactant(s) and product(s); as well as a balanced chemical reaction for
the step in the TCA (Krebs) cycle where isocitrate is converted to a-ketoglutarate (step 3 in the class
notes). (You don't need to draw the structures of coenzyme A (COA), NAD* or NADH.)
B. What enzymes catalyze steps 3 and 5 in the Kreb's cycle from the class notes?
C. Would you categorize step 8 in the TCA cycle where malate is converted to oxaloacetate as an oxidation or
reduction of malate?
D. Considering that some energy is spent transporting acetyl-CoA to mitochondria, how much net energy (in
kcal) is produced by converting 15 mol of glucose to CO₂ in the glycolysis & Krebs cycle pathways?
E. How many kcals of energy from oxidizing 15 mol of glucose to CO₂ (your answer to…
