Nitric oxide produced by the endothelial layer of blood vessels stimulates the smooth muscle layer underneath to relax, leading to widening of blood vessel lumen and subsequent decrease in blood pressure. This type of cellular communication between endothelial and smooth muscle cells is an example of what type of chemical signaling?

Which is true about signaling receptors? They are transmembrane proteins that have binding sites for extracellular activated proteinsto effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular DNA-binding proteins to effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular enzyme effectors to effect changes inside the cell. They are transmembrane proteins that have binding sites for extracellular messengers to effect changes inside the cell.
The fight-or-flight reaction prepares an animal to Pesponu Lu a threatening situation, by either fighting or running away. One aspect of this response is changes in blood flow such that the skeletal muscles and heart receive higher blood flow (vessels dilate) while digestive organs receive less (vessels constrict). A) Which signal molecule(s) is/are involved in this response, and how do they produce these changes in blood vessels? Briefly explain how this example illustrates how different cells are able to use the same ligands in different ways.
when kidney cells secrete low levels of oxygen in the blood they secrete erythropoietin. in this particular signaling pathway (response to low oxygen) the secretion of erythropoietin represents which step of the signal transdution process?
Proteases are enzymes that destroy proteins. Application of these enzymes to an intact cell strips the proteins off the cell surface. If a specific signaling molecule is added to cells stripped of surface proteins and the cell still responds, what must be true of the signaling pathway? The receptor is a ligand-gated ion channel. The signaling molecule doesn't need a receptor. The signal can directly activate the second messenger system and does not need to activate the receptor. The receptor for this signal is inside the cell, and the signaling molecule is nonpolar and can diffuse into the cell.
Which of these is NOT a response that occurs when an intercellular chemical signal binds to a membrane-bound receptor? 1. Enzymes at the inner surface of the cell are directly activated. 2. Ion channels open or close. 3. Enzymes add phosphate groups to certain proteins in the cell. 4. The chemical signal and receptor bind to DNA in the nucleus. 5. Activated G proteins activate enzymes that produce intracellular messengers.
What term is used to indicate signaling chemicals that bind to membrane receptors? Which type of membrane receptor is most important in directing intracellular events by promoting formation of second messengers?
When a signaling molecule binds to a receptor located in the cell membrane, the signal / information is carried further into the cell via the receptor. The signal / information will lead to some type of change inside in cells in response to the signal it received. What this change is depends on the type of signaling molecule that binds to the cell (but may also depend on the type of cell that the signaling molecule binds to). In some cases, the change that takes place in the cell will be rapid and take a few seconds off that the signaling molecule binds to the receptor until the change takes place (fast signaling pathway). In some cases the change will take much longer, perhaps several hours from the time the signaling molecule binds to the receptor until the change occurs in the cell (slow signaling pathway). Explain how the signal path would be be able to look when it is fast and what it could look like when it is slow.

Histamine is a chemical substance released in inflammatory and allergic response. The histamine H1 receptor is a G protein-coupled receptor that activates phospholipase C in response to the binding of histamine. Arrange the data below showing the process of histamine signal transduction from the H1 receptor. Calcium ions flow through ligand-gated ion channel. Phosphorylation cascade leads to the activation of a cellular response. Calcioum ions activate a protein, leading to a cellular response. Enzyme cleaves PIP2, forming DAG and IP3. Calcium iom concentration increases in the cytosol. IP3 binds to a ligand-gated ion channel in thw ER membrane.
