Glycogen is a stored form of glucose. It is a large multi-branched polymer of glucose which is accumulated in response to insulin and broken down into glucose in response to glucagon. When BGL levels are low, glycogen us broken down. This is important because it lets us know how low BGL are regulated.
When anyone eat, the carbohydrates(from your food) turn into glucose. Then the glucose levels increase. When the glucose levels increase, the insulin levels increase because the insulin makes sure the glucose stays at the homeostasis level.
Diabetes is a disease that affects the way the body turns sugar into energy. Type 1 diabetes is when your pancreas doesn't produce insulin and in type ll your pancreas produces little insulin but the body cells have low sensitivity to it. Blood glucose (sugar) stays in your blood. Then the cells don’t get enough sugar for fuel. The body doesn’t have enough energy to do its work. Over time, the high level of sugar in the blood can damage the body.
As shown in green and purple, the pancreas releases glucagon and insulin, to further regulate BGL. The insulin is released when BGL are too high. Insulin helps the body absorb the glucose, which lowers the blood sugar. Glucagon forces the liver to release stored glucose, which causes the blood sugar to rise. This is important because it explains the way our bodies maintain healthy levels. Both insulin and glucagon are released from islet cells in the pancreas.
People with diabetes have to use this. machine to find their blood glucose level. The average level is 70-99 mg/dL. First the person would have to prick their finger with the needle at the and and the machine finds their blood glucose level. Two hours after a meal your blood sugar should be under 140 mg/dL.
Insulin and glucagon are the key hormones involved in regulating blood glucose levels but they have opposite fashions. When blood glucose levels are too high, insulin is released from pancreas and goes to the liver. It tells the liver to absorb some glucose so the body can maintain homeostasis. Same for when its too low but glucagon is released then sent to liver and tells it to release glucose to blood to maintain homeostasis.
