Blood sugar regulation cells in the pancreatic islets are among the most well understood and important. If the blood glucose level falls to dangerous levels (as during very heavy exercise or lack of food for extended periods), 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 (this process is called glycogenolysis). The glucose is released into the bloodstream, increasing blood sugar. Hypoglycemia, the state of having low blood sugar, is treated by restoring the blood glucose level to normal by the ingestion or administration of dextrose
Cuban sugar economy price of 6.11 cents per pound from 1965 to 1970. Due to decreasing sugar prices after 1963, the Soviet Union paid almost twice the world price of sugar. Additionally, Cuba failed to increase its sugar production to the promised level of 10 million tons by 1970 resulted in the Soviet Union subsidizing Cuban sugar by more than $1.1 billion during this time.
