Following the binding of an extracellular signal molecule, receptor tyrosine kinases (RTKs) do which of the following? form dimers in which each polypeptide chain phosphorylates its own cytoplasmic tail form dimers in which each polypeptide chain cross-phosphorylates the cytoplasmic tail of its partner. become internalized so that they can phosphorylate and activate various intracellular signaling proteins rearrange their multiple membrane-spanning helices in a way that enables self-phosphorylation activate (or inactivate) the α and βγ subunits of G proteins

The signal that "tells" a ribosome to finish the translation of a protein into the RER instead of into the cytoplasm is called the SPSP (secretory pathway signal peptide). What exactly is the SPSP? Group of answer choices it is the first 20 amino acids of any protein that is going to be shipped through the RER secretory pathway (RER --> golgi --> membrane) it is a carbohydrate signal that added to any protein that is going to be shipped through the RER secretory pathway (RER --> golgi --> membrane) it is an internal signal within the polypeptide primary structure that is found after the translation is complete, and causes the protein to be shipped into the RER

An $\mathrm{S}-\mathrm{S}$ bond between two cysteine amino acids on a protein is called a(n) This bond stabilizes the tertiary structure of many proteins.
