What is protien s?
Protein S is a vitamin K-dependent plasma glycoprotein synthesized in the endothelium. In the circulation, Protein S exists in two forms: a free form and a complex form bound to complement protein C4b. In humans, protein S is encoded by the PROS1 gene.
Which of the following incorrectly matches the type of cell type of protein and site of the proteins synthesis?
prokaryote, plasma membrane protein, ribosome bound to plasma membrane
Which drug is binding with plasma protein?
Many drugs bind with your plasma proteins or albumins. An example is Warfarin (Coumadin) which is 90% bound to plasma proteins.
Can you donate plasma on lithium?
Taking lithium is an automatic 6 month deferral until after you stop taking the medication. Lithium is bound to plasma protein and interferes with plasma processing.
What correctly describes some aspect of protein secretion from prokaryotic cells?
Pretins that are secreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
Due to a conformational change of the receptor protein....
Will highly protein-bound drugs be metabolized quickly?
If a medication is protein-bound (i.e. albumin), they are not available for metabolism. Therefore, the more the drug is bound to protein, the less is metabolized.
What is a membrand bound organelle?
A membrane-bound organelle is an organelle surrounded by a plasma membrane.
What is DNA loosly bound to protein called?
The segments of DNA that are loosly bound to protein are called Chromatin.
Is warfarin a protein bound medication?
Yes it is, therefore you need to be careful when taking other protein bound medications.
In plasma iron is transported bound to what?
Transferrin
Where are the electrons in plasma found?
Plasma contains a small proportion of free electrons, which are not bound to any atoms and instead flow freely in the plasma.
