Explain how the hormone glucagon and insulin are antagonistic to each other in their action?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Hormones**: Begin by understanding that glucagon and insulin are both hormones produced by the pancreas, specifically from the islets of Langerhans. Glucagon is secreted by alpha cells, while insulin is secreted by beta cells.

2. **Function of Glucagon**: Glucagon is a peptide hormone that plays a crucial role in increasing blood glucose levels. When blood sugar levels drop, glucagon is released into the bloodstream, signaling the liver to convert stored glycogen into glucose and release it into the blood.

3. **Function of Insulin**: In contrast, insulin is also a peptide hormone that functions to decrease blood glucose levels. When blood sugar levels are high (such as after eating), insulin is released, promoting the uptake of glucose by cells and facilitating its storage as glycogen in the liver and muscle tissues.
