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…

Illustrate your understanding of metabolic pathways and mutations by responding to the guiding questions. Please also use this link ( https://rarediseases.org/rare-diseases/phenylketonuria/ ) for more information. Phenylketonuria (PKU) is an inherited disorder that is identified as an inborn error of metabolism. It is easily detectable during the first days of life through newborn screening tests. A drop of the infant’s blood can determine the presence of the enzyme that is responsible for processing the essential amino acid phenylalanine. With normal enzyme activity, phenylalanine is converted to another amino acid (tyrosine), which is then utilized by the body to produce melanin (pigmentation in hair, skin, eyes), thyroid and other hormones. However, when the phenylalanine hydroxylase enzyme is absent or deficient, phenylalanine abnormally accumulates in the blood. A…arrow_forward
