- B) Read the situations below and indicate which of the four methods of enzyme regulation is occurring for each. a) The energy-carrying molecule ATP is made by the enzyme ATP synthase. Muscle cells use a lot of energy and also have higher amounts of the ATP synthase enzyme than many ouier cem types. General mechanism of enzyme regulation: /1 b) Prostaglandins are messenger molecules involved in the inflammatory response, as well as th perception of pain. They are synthesized from polyunsaturated fatty acid substrates by an enzyn called cyclo-oxygenase. "Ibuprofen" is the active ingredient in a variety of anti-inflammatory medications such as Motrin® and Advil®. It reduces pain and swelling by binding to a hydrophobic channel in the active site of cyclo-oxygenase, blocking the polyunsaturated fatty acids from binding to the enzyme, and therefore stopping production of prostaglandins. General mechanism of enzyme regulation: a) In point form, describe the steps by which ATP is produced…A plot of the velocity v, or rate, of an enzymatic reaction vs. the substrate concentration [S] that is sigmoid or S abaned instead of hyperbolic is characteristic of: a) b) allosteric enzymes modulator proteins isozymes proenzymes zymogensIdentify the type of regulation of enzyme activity seen in the following situations - for example, competitive inhibition, allosterism, phosphorylation, zymogen conversion, association-dissociation, feedback inhibition, etc. a. Trypinsogen, which is not catalytically active, is converted to the active enzyme trypsin by removal of a hexapeptide from the N-terminal end. b. The dimer protein kinases is catalytically inactive. Binding of cAMP causes protein kinase dimer to split into its monomer which are active catalysts.
- mTOR is a cytoplasmic kinase that regulates cell division. Its misregulation can lead to cancer. The canonical mTOR inhibitor, rapamycin, is FDA approved as a cancer treatment. Rapamycin is an allosteric inhibitor that does not bind anywhere near the substrate binding site of the enzyme. A) What is the name of this type of inhibition? B) Sketch a REPRESENTATIVE double-reciprocal/Lineweaver-Burke plot that includes the enzyme kinetics for BOTH the uninhibited and inhibited reaction. Be sure to: 1) Make ABSOLUTELY clear which curve is your uninhibited reaction and which is your inhibited reaction. 2) Label the X and Y axes. 3) Indicate what the X- and Y-intercepts represent with regards to Michaelis-Menten kinetics. C) Can increasing the substrate concentration overcome this type of inhibition? Explain in a sentence or two.If you can clearly visualize the chymotrypsin mechanism of action, you should be able to picture the structure of the transition state right after the enzyme attacks the first substrate. Think hard about what we have covered, and visualize that transition state accurately:What are the effects of different light colors in photosynthesis?

- I have a fill in the blank question. "1) Heterophobic or Homotrophic effects= are changes in affinity due to substrate binding and cooperativity between different subunits. They give Allosteric rate curves their Sigmoid shape. 2) Hetero or Homotrophic effects=are changes in affinity due to binding of an effector to an Allosteric site. Allosteric sites are usually 3)located outside or inside the active site. Positive Allosteric effectors (activators) shift the rate curve 4) Left or Right, where Negative effectors shift it 5) right or left. Positive Allosteric effectors usually stabalize the 6)T or R state. Negative efftors usually satbalize the R state."
