Starting with a hydrophilic signaling molecule, describe the process that takes place with a G-coupled protein signaling pathway.  Assume that cAMP is your main secondary messenger.    Be sure to include in your answer: 1) a description of the receptor 2) a description of the structure of the G-protein (inactive and active […]

The Effect of low pH on Enzyme Activity Design an experiment in which you will test the effect of an acidic fluid on enzymatic activity. (Recall: enzymes are proteins.) To complete this project, it may be useful for you to review the Scientific Method Tutorial (found the Course Content section […]

Q1. Recall that the complex oxidation of a mole of glucose releases 686 kcal of energy. The phosphorylation of ADP to form ATP stores approximately 7.3 kcal per mole o ATP. What is the approximate efficiency of cellular respiration for a “mutant” organism that produces only 29 mole of ATP […]

In the signal transduction lecture , we established that the BCR-ABL translocation creates a membrane bound receptor with constitutive kinase activity. What defect is associated with this oncogenic mutation? A. An increase in phosphorylation of the substrate (compared to wild type)B. A defect that attenuates signaling from the BCR-ABL kinaseC. […]
