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:
Explanation:
Glucose is a sugar, highly soluble in water because it has lots of polar hydroxyl groups (-OH) which can form hydrogen-bonds with water molecules. These types of bonds are intermolecular forces which are present in other macromolecules like the DNA or proteins.
Cholesterol and triglycerids are lipids. These have long chains of hydrocarbons, which are non polar and therefore insoluble in water.
Blood is made of a solid and a liquid part. <u>The solid part contains cells</u>. <u>The liquid part (plasma), is made of water, salts, and proteins</u>. Glucose and cholesterol/triglycerids travel in the liquid part of the blood, in an aqueous environment. Because the lipids are not soluble, they need to travel with a carrier protein that keeps them protected from the surrounding water.
