Which immunoglobulin is delivered in Colostrum, and found in the mucous membranes?
IgA
Which immunoglobulin is associated with parasitic immunity?
IgE
What is the most common Immunoglobulin?
IgG
Which immunoglobulin is found on the surface of B-Cells but has a relatively unknown function?
IgD
Haptoglobin, Haemopexin and Methemalbumin serve what function?
Cleanup of Haemoglobin debris
Where is IgM usually located?
in the intravascular space
Which immunoglobulin is a major component of colostrum?
IgA
Rare cases of isolated deficiency of which immunoglobulin are found to be associated with no obvious pathology?
IgD
Which immunoglobulin is found in the intravascular space and is considered the first immunoglobulin responder?
IgM
The morphologic deformity of erythrocytes in Sickle Cell Anaemia is a result of a genetic change in what component of the cell?
Haemoglobin proteins
What effect does haemoglobin have on the ability of the blood to carry oxygen?
67-fold increase in capacity
Which principle describes the pH effect of oxygen binding and Haemoglobin?
the Bohr effect
Why does foetal haemoglobin (HbF) have a different saturation curve to Haemoglobin (Hb)?
So the blood of the foetus can extract oxygen from the blood of the mother
IgA appears to function as the primary immunologic barrier in what tissues?
Mucous Membranes
Which Immunoglobulin circulates as a pentamer?
IgM
Is haemoglobin an absolute requirement for oxygen to be dissolved in the blood?
No
Which molecule has the higher affinity for oxygen - Myoglobin, or Haemoglobin?
Myoglobin
What is an important allosteric effector of Hb, which is often found in adaptations to high altitude environments?
2,3-Bisphosphoglycerate
The two IgA molecules forming dimerized IgA are linked by a molecule called:
J Chain
Indicators of anaerobic metabolism such as 2,3-Bisphosphoglycerate have what effect on hemoglobin?
encourage Hb to give up oxygen
Which immunoglobulin plays a major part in allergies and atopy?
IgE
What protein is a relative of haemoglobin, found only in muscle tissue?
Myoglobin
The Bohr effect describes an increased pH causing an increase or decrease in the O2 affinity of Hb?
Decrease
Which immunoglobulin eliminates small, soluble antigenic proteins via enhanced phagocytosis?
IgG
