Acetyl CoA transfers an acyl group to ________ to form ________ in the Krebs cycle.
Krebs cycle fill in the blank...
In reaction 1 of the Krebs cycle, acetyl-CoA formed in the pyruvate dehydrogenase reaction condenses with the four-carbon compound to form with the elimination of coenzyme A. Since the product has three carboxyl groups, this pathway is referred to as the cycle. In reaction 2 of the Krebs cycle, this product then undergoes to form The enzyme is called aconitase because the compound cis-aconitate is a(n) of the reaction. Reaction 3 eliminates CO_2 to...
List 3 macromolecular sources for acetyl CoA that can be used in the Krebs Cycle. Which of the macromolecular sources produces more ATP per molecule and briefly state why.
In cellular respiration, oxygen is required by: glycolysis electron transport chain Krebs cycle Acetyl CoA production
Choose the Products of the Krebs Cycle. Select one or more: FADH2 ATP CO2 Acetyl COA Pyruvic Acid NADH Proton Gradient
Draw the complete TCA cycle (Krebs or Citric acid cycle). Show the entry of acetyl- COA and the eight intermediates. Draw the chemical structures of each compound. Show the control point(s) in the pathway. Show where all CO2 is released and label the reactions where oxidation of carbon occurs.
How many CO2 molecules are produced during glycolysis, acetyl-CoA transformation reactions, and the Krebs cycle per molecule of glucose? Why is this number significant? Where does the CO2 go?

8. The citric acid cycle requires acetyl-CoA to begin. Describe how acetyl-CoA is produced for the citric acid cycle.
Acetyl-CoA labeled with C, as shown, can enter the citric acid cycle. Assuming all the acetyl-CoA enters the cycle... 1. What fraction of the label will be present in oxaloacetate at the end of one turn of the cycle? 14 2. Which carbons in the oxaloacetate formed by one turn of the cycle would contain the radioactive label? C4 C3 C2 Ci .What fraction of the original radiolabel present in the acetyl-CoA will be present in oxaloacetate at the end...
Why is the conversion of pyruvate to acetyl-CoA considered irreversible in animals? Why is acetyl-CoA only considered ketogenic and not glucogenic, even though it enters the TCA cycle to form citrate? How do plants make acetyl-CoA glucogenic?
