| Question | Answer |
| these proteins have multiple protein binding domains and can form multi-protein complexes for signal transduction | |
| hydrophilic molecules generally bind to _____ receptors. | |
| these receptors transduce signals across the plasma membrane via changes in receptor protein conformation that lead to changes in receptor protein activity and/or receptor protein | |
| enzyme that phosphorylates protein target | |
| release mechanism for catecholamine hormones | |
| thyroid hormones bind which type of receptor? (cell surface or intracellular) | |
| release mechanism for thyroid hormones | |
| PKA catalytic subunits phosphorylate what? | |
| this type of receptor protein is a channel for ion transport | |
| this term describes steps that “transduce” signal binding to receptor into cellular response(s) | |
| which subunit of the G-protein binds GTP and GDP? | |
| these receptors bind to signaling molecules that do not diffuse into cell | |
| Cytosolic domain of this receptor either has intrinsic enzymatic activity or activates an associated enzyme. There is no enzyme activity without ligand. | |
| these enzymes remove phosphate groups added by kinases | |
| this protein inactivates G protein | |
| G proteins are active when what molecule is bound? | |
| Phosphotyrosines recruit which adaptor protein | |
