The secretion of insulin into the bloodstream is done through exocytosis and absorption through the capillary arteries.
Insulin is a protein required to process sugar. This is a <u>naturally produced protein</u> for which the pancreas is responsible. The insulin Protein is considered a transport protein. It is responsible for carrying glucose from the bloodstream into cells to be used as energy.
This protein is of vital importance. The secretion of this protein is done through exocytosis, which means that after passing through the ribosomes and the Golgi, it is contained within a membrane, which will then fuse into the plasmatic membrane and be released from the cell. It is then absorbed through the capillaries to enter the bloodstream.

Answer:
Frederick Griffith was the first scientist who discovered that cell contains some components that can be transferred to another cell and cause a permanent change(transformation) in the new cell.
To prove this he performed an experiment in which he took two strains of <em>Streptococcus pneumoniae</em> which contain one rough strain and one smooth strain. Rough strain was non-virulent strain and smooth strain was virulent strain.
So he injected smooth and rough strain in mice and saw that mice die when virulent strain is injected and survive when non-virulent strain is injected. Then he injected heat killed virulent strain in which mice survived.
Then he added remain of heat killed bacteria with live smooth strain of bacteria and infected the mice and saw that the mice was killed by non-virulent smooth strain of streptococcus.
After this experiment he concluded that cells contain some component later identified as DNA which can be transferred to new population of cells and transform these new cells.
