Explain why having two hormones with opposite effects allows the body to achieve blood glucose homeostasis.

The body maintains blood glucose homeostasis through the balanced actions of two hormones: insulin and glucagon. These hormones have opposite effects on blood glucose levels, which allows for fine-tuned regulation.

1. Insulin: This hormone is produced by the beta cells of the pancreas. When blood glucose levels are high, such as after a meal, insulin is released. Insulin promotes the uptake of glucose into cells, particularly muscle and fat cells. It also promotes the storage of excess glucose as glycogen in the liver. These actions lower blood glucose levels.

2. Glucagon: This hormone is produced by the alpha cells of the pancreas. When blood glucose levels are low, such as during fasting or between meals, glucagon is released. Glucagon promotes the breakdown
