What is vasoconstriction?
Vasoconstriction is the constriction or narrowing of blood vessels by small muscles in their walls, slowing or blocking blood flow. Vasoconstriction is the constriction of blood vessels that increases blood pressure.
How does aspirin work to inhibit platelet aggregation?
Aspirin works by blocking an enzyme called cyclooxygenase, which is needed for the production of certain chemicals that promote platelet aggregation. By inhibiting this enzyme, aspirin helps prevent platelets from sticking together and forming blood clots.
Does propranolol cause vasoconstriction?
Yes it does. The first person who answered it was wrong, dead wrong. Just look at the first page of results. It lowers your heart rate to decrease blood pressure. Blocking the beta receptors results in vasoconstriction.
Do ganglionic blockers increase the effects of vasodilators?
Neural transmission within the ganglia is cholinergic (acetylcholine) and the vasoconstrictive neurons release epinephrine at the blood vessels. So blocking neural transmission within the ganglia will reduce vasoconstriction.
Where cycloheximide inhibit protein synthesis?
Cycloheximide inhibits protein synthesis in eukaryotic cells by blocking translocation on the ribosome. It binds to the 60S subunit of the ribosome and prevents the elongation of the polypeptide chain during translation. This stops the synthesis of new proteins, leading to the disruption of cellular processes that rely on protein production.
How do you stop protein synthesis?
Protein synthesis can be stopped by blocking translation, primarily by inhibiting the functions of ribosomes or tRNA molecules in the cell. For example, antibiotics like puromycin can prematurely terminate protein synthesis by mimicking the structure of aminoacyl-tRNA and binding to the A site on the ribosome. Additionally, certain drugs or compounds can target key components of the translation machinery to halt protein synthesis.
How does vasoconstriction and vasodilation of blood vessels effect blood pressure?
No. Vasoconstriction is a squeezing of the veins. This is like putting your thumb at the end of a garden hose. The constriction of the flow increases the pressure. The water shoots out faster from the hose when your thumb is blocking the way. If the entire hose were to tighten, as in vasoconstriction, the same effect happens.--From Wikipedia: Vasoconstriction"Generalized vasoconstriction usually results in an increase in systemic blood pressure..."
The antibiotic cycloheximide binds to the 60S subunit of the ribosome as shown in Figure 20.2 The effect is to?
Prevent polypeptide elongation in eukaryotes.
What does not blocking mean in drama?
not blocking means where you do not stand in font of someone (not blocking them)
