Based on the information provided, what do you think the most ideal parameters would be for optimal glucose production?
Marysya12 [62]

The most ideal parameters for optimal glucose production are insulin sensitivity SI, glucose effectiveness SG, insulin action p2 and the volume of distribution of glucose V.

<h3>What is used for glucose production?</h3>

Insulin, glucagon, and hepatocyte-derived factors are used in these activities. Gut: Hormones are released in the gut in response to nutrition intake. These hormones affect hunger, stomach emptying, glucose production, and glucose elimination.

After eating, the beta cells release insulin into the bloodstream as your blood glucose levels rise. In order for glucose to enter muscle, fat, and liver cells, insulin works as a key to unlocking those cells. The majority of the cells in your body use glucose, lipids, and amino acids (the components of protein) as fuel.

By converting glycogen into glucose, a process known as glycogenolysis, the liver produces sugar or glucose. Additionally, the liver may produce the sugar or glucose that is required by harvesting amino acids, waste, and fat.
