Which of the choices below is the parent cell for all formed elements of blood?

Ostrovityanka [42]

Answer:

The hemocytoblast (option B) are the parent cell for all formed elements of blood

Explanation:

All blood cells are originated from a common stem cell, which is called a pluripotent stem cell. It is capable of giving rise to any of the blood cells maintaining its existence through mitosis. By dividing pluripotent stem cells, new cells are originated, which become multipotent and differentiate into lymphoid (NK cell and the polymorphonuclear cell) or myeloid cells (megakaryocite); always respecting the original quantity.

Insulin is synthesized in the form of a precursor proteinthat requires cleavage of two different peptide segmentsbefore the matu

IgorC [24]

Answer:

C.Mature secretory vesicles

Explanation:

Hello!

Insulin is synthesized in pancreatic ß-cells. It is a small protein formed by two amino acid chains (A-chain, 21aa, and B-chain, 30aa) connected by two disulfuric chains.

The gene encoding is located in the short arm of chromosome 11. Its precursor, called preproinsulin, is synthesized in the endoplasmic reticulum. Right after its synthesis, this protein undergoes enzymatic cleavage to proinsulin (86 aa).

The prohormone is packed in small granules within the Golgi complex, that migrates to the cell surface. As the granules mature, 3 proteases split the proinsulin into equal amounts of insulin and C-peptide.

These secretory granules are stored within the intracellular space until their contents are released by exocytosis.

I hope you have a SUPER day!
