These antibodies are IgD.
It is a monomeric antibody isotype that is expressed in the plasma membranes of immature B-lymphocytes. It is also produced in a secreted form that is found in small amounts in blood serum. IgD is co-expressed with IgM on the surface of the majority of mature B cells prior to antigenic stimulation and functions as a transmembrane antigen receptor.
Answer:
acceleration due to gravity: g= 9 m/s^2
Explanation:
m=2kg
w= 18 n
w=mg
g= w/m
g=18/2
g= 9m/s^2
False
I hope this helps you with your question
Answer: (B) to function as the final electron acceptor in the electron transport chain.
Explanation:
Oxidative phosphorylation is a process that takes place in cellular respiration. It consists of two component pathways which includes the electron transport chain (etc) and chemiosmosis.
In etc the electrons are passed from one to another molecule, the energy is released by the electrochemical gradient.
In chemiosmosis, the energy stored in the electrochemical gradient is used to produce energy molecules in the form of ATP (Adenosine triphosphate).
The oxygen is present at the end of the etc. It's function is to accept the electrons also picks up the protons to form water. If oxygen is absent then no molecule will accept the electrons, the electron transport chain will stop. There will be no chemiosmosis as the ATP will not be produced in the absence of formation of a electron gradient.
