Explanation / Answer

Answer : The correct option is D (Blood sugar levels fall below 100mg/dl --- Low blood sugar travels through body --- Pancreas sense the change in blood level ---Glucagon is released)

Explanation : When the blood glucose level falls as a result of muscular activity or exercise the Alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels. They convert glycogen into glucose (glycogenolysis). The glucose is released into the bloodstream, increasing blood sugar, which can be used by muscle cells for doing work.

When levels of blood sugar rise, whether as a result of glycogen conversion, or from digestion of a meal, insulin hormone is released from beta cells found in the Islets of Langerhans in the pancreas. This hormone, causes the liver to convert more glucose into glycogen (glycogenesis), and to force about 2/3 of body cells (primarily muscle and fat tissue cells) to take up glucose from the blood thus decreasing blood sugar. Therefore Insulin and glucagon together regulate the blood glucose levels.
