Which cellular molecule will have an antagonistic action to the effects of adenylyl cyclase?glycogen phosphorylaseGαlpha-GTPphosphodiesterasecAMPNone of the aboveA defective hepatocyte was isolated from a liver cancer patient. This hepatocyte contains approximately 75+ active protein kinase A (PKA) molecules, even in the absence of epinephrine. What is a plausible explanation?The cell’s adenylate cyclase gene has a mutation that makes the cyclase inactive all of the time.The cell’s phosphorylase kinase gene has a mutation that makes the kinase active all of the time.The cell’s adenylate cyclase gene has a mutation that makes the cyclase active all of the time.The cell’s glycogen phosphorylase gene has a mutation that makes the phosphorylase active all of the time.None of the above.The carbon that enters the carbon assimilation reactions of photosynthesis is __________ to form triose phosphatesoxidized by ATPreduced by ATPreduced by NADPHoxidized by NADPHreduced and phosphorylated by NADPHMicrotubules are involved in all of the following EXCEPTthe formation of the spindle apparatus during cell divisionthe extension of the lamellopodium of a white blood cell during cell locomotionthe formation of flagella used by sperm cells to swimtransport of vesicles between organelles of the endomembrane systemMicrotubules are involved in all of the above.Which of the following is NOT true concerning the chloroplasts and mitochondria and therefore is not evidence to support the endosymbiotic theory?Both are surrounded by a double membrane.Both divide by binary fission.Both contain their own circular genome.Both can survive independently from a eukaryotic cell.All of the above are TRUE, and support the endosymbiotic theory.
