In my biology class this specific questions was asked. A cell secretes a hormone through facilitated diffusion.
INSULIN
They bond to receptor sites on their target cells to facilitate some reaction, depending on the hormone. For example, insulin is a protein hormone that bonds on receptor sites on muscle cells to allow the diffusion of glucose into the muscle cell. Without insulin, the cell membrane is impermeable to glucose, but the insulin bridge made when the hormone bonds with receptors on the muscle cell membrane allows for the glucose to pass through. This is called facilitated diffusion.
Glucose is a sugar.It is not a hormone.
Glucagon is the hormone that raises blood glucose levels.
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
insulin hormone
No, but insulin is a hormone that regulates the body's production of glucose.
growrh hormone
It is a hormone by pancreas.It increase blood glucose level.
No, growth hormone is not glucose sparing. Growth hormone stimulates the breakdown of stored glycogen (a form of glucose) in the liver, leading to an increase in blood glucose levels. This increase in blood glucose helps to provide energy for growth and other metabolic processes.
When blood glucose levels drop, the pancreas releases the hormone glucagon, which signals the liver to release glucose into the bloodstream.
