Using this information and the image provided, describe the reaction catalyzed by an esterase and classify it as one of the 6 classes of enzymes.  The insert also tells you that Enalaprilat (the active form of Enalapril) targets angiotensin-converting enzyme (ACE), which cleaves the blood-pressure regulating peptide angiotensin I. The active form of the drug looks very similar to the endogenous substrate of the enzyme ACE.  Based on this information, what type of interaction is occurring between Enalaprilat and ACE?  Propose how the presence of Enalaprilat changes the overall reaction.

*In the presence of saturating amounts of oxaloacetate, the activity of citrate synthase from pig heart tissue shows a sigmoidal dependence on the concentration of acetyl-SCOA as shown below. SCOA is added, the curve shifts to the right and becomes even more sigmoidal. On the basis of these observations, explain how succinyl- SCOA regulates the activity of citrate synthase. Why is succinyl-SCOA an appropriate signal for regulation of the citric acid cycle? does the regulation of citrate synthase control the rate of cellular respiration in pig heart tissue? 100 - 80 succinyl-CoA Activity (% of V, 60 40- No Succinyl-CoA added 20 40 60 80 100 120 [Acetyl-CoAl(pM) - How -
