Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.

Which of the following correctly describes cholera toxin and its effect on intestinal epithelial cells? O Cholera toxin.is an extracellular signal that decreases adenylyl cyclase activity. O Cholera toxin is an extracellular signal that increases the dephosphorylation of protein kinase A. O Cholera toxin is an intracellular signal that decreases intracellular CAMP concentration. O Cholera toxin is an intracellular signal that increases extracellular chloride ion concentration.
The S (spike) glycoprotein of coronaviruses can engage receptors by the N-terminal domain, the C-terminal domain, or both. The C-terminal domains of both human SARS coronaviruses bind ACE2 (angiotensin-converting enzyme 2), whereas that of MERS-CoV binds DDP4 (dipeptidyl peptidase 4). In contrast, in mouse hepatitis coronavirus (MHV) the N-terminal domain of S binds CEACAM (cell adhesion molecule 1). You have identified a novel coronavirus with an S protein that displays similarity to MHV at the N terminus and to SARS at the C terminus. What are the molecules most likely to function as receptors and how will you test this?

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.
