.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
Answer:
. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate
The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.
The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.
5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.
The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
