ketoacidosis

Explanation / Answer

1. Glucagon and insulin are secreted by the alpha and beta cells of islets of Langerhans in pancreas respectively. The control glucose production, triacylglycerol deposition, and protein synthesis. Glucagon acts as a catabolic hormone, while insulin acts as an anabolic hormone. Glucagon causes the breakdown of glycogen into glucose while insulin induces the formation of glycogen from glucose. Hence, glucagon promotes glycolysis while insulin promotes glycogenesis. High insulin to glucagon ratio (IGR) stimulates glycogenesis, which is the formation of glycogen from glucose.

Option is glycogenesis

2. When blood sugar decreases, the pancreas is stimulated to secrete glucagon. The glucagon will enter the liver and stimulate breakdown of glycogen to glucose. Blood glucose is lowest at fasting. Hence, glucagon levels will be high. When food is ingested, glucagon levels will slowly decline, as glucose will be derived from digested food. Blood sugar levels will come back to after meal levels after 2 hours. This is the reason why blood glucose levels are tested for diabetes after 2 hrs, to indicate whether insulin can convert glucose to glycogen. Hence, blood glucose levels will be highest at 1 hour post meal, and glucagon levels will be lowest at this point.

Option is B. one hour post meal.

3. Insulin is an anabolic hormone that is secreted by pancreas when glucose levels are high in blood. It induces the conversion of glucose to glycogen by glycogenesis. Hence, its levels will be high when blood glucose levels are high and its levels will be low when blood glucose levels decrease in blood.

Option is A: is stimulated by increasing blood glucose levels and inhibited by low blood glucose levels.
