What type of molecules serve as ligands for intracellular vs. membrane receptors?

3) The “Met" receptor is a membrane receptor protein responsible for initiating signal transduction pathways that cause cells to divide, among other things. After the Met receptor has been stimulated by its specific growth factor, another protein called c- Cbl will bind to the Met receptor. C-Cbl will then attach a chain of small proteins called ubiquitin to the Met receptor. These chains of ubiquitin help the cell recognize that the Met receptor should undergo receptor-mediated endocytosis, which eventually leads to the destruction of the Met receptor. Circle any answer or answers that include mutations that could cause the cell to potentially become a cancer cell. A) a mutation causing there to be too much ubiquitin protein produced. B) a mutation causing c-Cbl to be inactivated. C) a mutation causing ubiquitin to be inactivated. D) a mutation causing there to be too few Met receptors produced. E) a mutation causing the Met receptor to no longer be able to bind to its growth factor.…

40. Notch receptors operate through juxtacrine signaling which requires A. close physical association between the signal-emitting and signal-receiving cells B. cells far away from each other communicating through chemical messengers C. a cell to release a ligand that binds to a receptor on its own surface D. None of the above
