Converting Glucose to Fat or ATP?

[Mithril]

Thank you so much! It didn't make much sense before because I wasn't sure which parts of it were important for my answer.

Insulin is a hormone secreted by the pancreas. It signals to cells to take up the glucose in the blood. Some glucose is needed immediately for energy. The rest is stored away in glycogen reserves in the liver and muscle. When the glycogen stores are filled, leftover glucose is converted into fat, and stored in that way (this process is not reversible, i.e. you cannot convert free fatty acids into glucose). I hope this helps!
