Sagot :
insulin and glucagon, are both are secreted from islets of Langerhans at the pancreas
Answer: Insulin and glucagon, secreted by the pancreas.
Explanation:
Insulin and glucagon are enzymes secreted by the pancreas and they work together in a negative feedback loop because one event triggers another, and then another to keep the glucose levels balanced in blood.
Glucose comes from the food and moves through the bloodstream. And when the glucose is in the bloodstream, it signals the pancreas to produce insulin. This hormone makes glucose to move into the cells and it will be used during cellular respiration to produce energy. When there is glucose that is not needed, glycogen is formed, which is a polysaccharide of glucose that serves as a form of energy storage.
On the other hand, glucagon works to counterbalance the actions of insulin when the glucose levels in your blood decrease. This hormone signals the liver and muscle cells to change the stored glycogen back into glucose. These cells then release the glucose into your bloodstream so the cells can use it for energy.
