Insulin production
Beta cells in the pancreas produce insulin, which secrete it daily at 3050 units at the healthy adult
. How insulin works when you eat
Insulin  starts to rise after eating about 8-10 minutes, and increases to a high  level after half an hour to an hour only a quarter of the food, and  returns to normal after 90120 minutes of eating, and glucose is one of  the most stimuli that Helps produce insulin, and its production may be affected by many different neurotransmitter and hormonal factors
Insulin secretion
The pancreas secrete insulin in two phases 

 Early stage
Which  is when the level of glucose is high; insulin is excreted to a large  extent to the level of glucose, which explains the incidence of low  sugar in some people who have performed a hysterectomy or part of the  small intestine, where they increase the proportion of insulin with no The presence of sufficient space for absorption, leading to a  disproportion between the low level of glucose, and the high level of  insulin, and thus gradually decrease
Late stage
Insulin  starts at this stage rising exponentially, when the body is getting  glucose from outside the body such as food, and this happens for more  than four hours, and it can occur at high glucose due to internal  effects in the body, and this occurs for more than 24 An  hour, which explains the high sugar in some people without diabetes,  when the proliferation of foods containing sugars, carbohydrates

 Insulin exit
Of  a beta cell. Insulin comes out of the cell when a large amount of  glucose is present in it. At the height of ATP, this process is called  the energy process within the cell
Insulin binding with receptors
The  receptors are the link between the inner medium of the cell and its  outer center. After insulin is released from the cell, it begins to  search for these receptors to host. These receptors are located on the  surfaces of the cells spread throughout the body

Glucose Transfer Glucose is transported throughout the body to be  converted to energy for use, via the feast of distributed vectors in the  body called (GLUT)
Carrier 1
This carrier is present in all tissues of the human body where it transfers the basic requirement.
Blood 2
This carrier is the carrier of glucose inside the beta cells, working under high glucose to secrete more insulin.
Carrier 3
In all tissues, it is the primary carrier within the nerve tissue.
Blood 4
This is found in the motor muscle and fatty tissue.
Carrier 5
This carrier is found in the brushes of human digestive cells, liver, and sperm. Carrier 6:
This is found in the liver and some other tissues
Carrier 7
These vectors exist in the digestive tract and kidneys to re-absorb glucose. Carotid 1 Found in the intestines and renal tubes Carotid 2 Found in renal tubules
