Which of the following could result in the continuous activation of a cell signalling pathway? A. A mutation resulting in the inactivation of a protein kinase. B. A mutation resulting in a ligand gated ion channel being unable to open. C. A mutation resulting in the inactivation of adenylyl cyclase that forms cAMP. D. A mutation resulting in a receptor tyrosine kinase always being found as a dimer.

Step 1
A mutation resulting in the inactivation of a protein kinase would actually result in the opposite effect - the cell signalling pathway would be inhibited or turned off. B. A mutation resulting in a ligand gated ion channel being unable to open would also result Show more…

An example of signal transduction amplification that occurs as a result of a single receptor binding to a ligand is: a. The receptor is itself a receptor tyrosine kinase which becomes active and phosphorylates a substrate every 10 milliseconds. b. When the receptor causes a release of sequestered calcium stores in the endoplasmic reticulum. c. The universal change in a receptor when it binds to a ligand. d. Two of the above. None of the above.

signal transduction pathways involving phosphorylation of a series of proteins is generally associated with which of the following events? a. production of cAMP in the process of signal transduction b. structure changes to each protein in the series, leading to changes in function c. release of Ca 2+ into the cytosol d. activation of a ligand-gated ion channel e. binding of a hormone to an intracellular receptor
