And what that means is our body will begin to break down the carbohydrates, the polysaccharides, into their individual units, glucose molecules. And so following a meal that is rich in carbohydrates, we see that inside our blood, the glucose levels will begin to increase. And the rise in concentration of glucose in the blood can actually be very dangerous, very toxic to our body. And so what the body does is it responds by stimulating the beta cells of the eyelids of Langerhine that are part of the pancreas to release insulin molecules into the blood. And insulin is a small peptide hormone. Now, what insulin does is it initiates this signal transduction pathway.
