Insulin and glucagon are two important hormones that help keep our energy levels balanced.

1. What Insulin Does:

   • Insulin is made by special cells in the pancreas when blood sugar (glucose) levels go over 100 mg/dL.
   • It helps:
     • Move glucose into muscle and fat cells so they can use it for energy.
     • Store glucose in the liver and muscles as glycogen.
     • Turn extra glucose into fatty acids, which are a type of fat.

2. What Glucagon Does:

   • Glucagon is released by different cells in the pancreas when blood sugar levels drop below 70 mg/dL.
   • It helps:
     • Break down glycogen in the liver and muscles to release glucose back into the blood.
     • Create glucose in the liver from things that are not carbohydrates, like proteins.
     • Break down fat in fat cells, releasing fatty acids for energy.

These two hormones work against each other to keep blood sugar levels between 70 and 130 mg/dL. This balance is important for our body to function properly.
