Energy, in the form of sugar, is transported in the note. It is carried throughout the body and into solely cells to produce ATP. ATP is needed for all cellular military action of the body. It is essential that the blood can maintain the bodys fuel at a constant level (homeostasis) regardless of how long it has been since the dying meal.
There are three main organs that regulate the check over of blood sugar: the pancreas, the liver and the adrenal glands. The pancreas produces hormones called insulin and glucagon. These hormones work antagonistically to maintain blood sugar levels that are neither to a fault low or too high. The adrenal gland plays a key function in making sure blood sugar levels are high enough. The liver helps with sugar metabolism by creating insulin receptor sites.
After a meal, insulin directs the flow of nutrients. This promotes fuel reposition in the liver, adipose create from raw stuff and in muscles. The flow of nutrients during self-control is influenced by glucagon. Once glycogen stores are depleted, muscle protein is degraded, and amino acids are used for gluconeogenesis in the liver. Triglycerides stored in adipose tissue are broken down under the fasting condition.
The dousing of glucose in the blood rises rapidly after the ingestion of glucose ( in a high carbohyd stride meal).
Insulin carries out its function and starts to express blood glucose concentrations back down to normal, then this removes the stimulus that tells the genus Beta cells to secrete the insulin in the first place. As a result, the of import cells become less and less stimulated and so the rate of secretion of insulin declines in parallel to the rate of decline in blood glucose concentration. This mechanism is referred to as negative feedback.
