What is the monovalent radical that consists of two atoms?
The monovalent radical that consists of two atoms is the hydride ion (H-). It has a single negative charge and is composed of two hydrogen atoms.
Which term describes any substance that the body regards as foreign?
Antigen.
Can a receptor be an antigen?
No, they are entirely two different things. What might stimulate a receptor could be an antigen.
Is T cell activation antigen specific?
Yes, T cell activation is antigen-specific. T cells recognize specific antigenic peptides presented by antigen-presenting cells through the T cell receptor (TCR). This interaction leads to T cell activation and the initiation of an immune response against the specific antigen.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
What are the specific charges of sodium and chloride?
Sodium is monovalent, the cation is Na+. Chlorine is monovalent, the anion is Cl-.
Is sodium chloride monovalent?
Sodium chloride is a compound and hasn't valence; sodium and chlorine, as elements are monovalent,
What is charge on monovalent ion?
The charge on a monovalent ion is +1, meaning it has lost one electron and carries a positive charge. Examples of monovalent ions include sodium (Na+) and chloride (Cl-).
Is copper monovalent or divalent?
Copper can exist in both monovalent (Cu+) and divalent (Cu2+) states, depending on the chemical conditions. In most common situations, copper tends to exist in its divalent form.
Are copper gold aluminum lithium have multiple valences?
Lithium is only monovalent. Aluminium is trivalent; rarely is bivalent or divalent. Gold is monovalent or trivalent.
What are monovalent metals?
Monovalent metals are metals that can form ions with a charge of +1. Examples of monovalent metals include lithium (Li), sodium (Na), and potassium (K). These metals typically lose one electron to achieve a stable electron configuration.
What is the molecule that can be recognized by the immune system?
Antigens.
Are monovalent electrons behaves like superconductors?
yes
What are the oxidation numbers for lithium?
+1. Lithium is monovalent.
Sodium ions are?
Na+ ions (monovalent +1)
What is antigen in German?
Abwehrstoff or Antigen
In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
