In everyday life, we rarely stop to think about all the intricate processes that continuously occur in our body. What happens to blood sugar levels when one skips lunch, runs a marathon, or eats spaghetti and a piece of chocolate cake? What do our cells do with all that sugar?
This learning program is designed to introduce you to blood glucose regulation. The program begins with an overview of the concept of homeostasis. You will then learn about the organs, tissues, cells, and molecules involved in the maintenance of blood glucose homeostasis. Finally, you will learn about the fate of glucose within cells.
Upon completion of this learning program, you will be able to::
Demonstrate the importance of blood glucose homeostasis.
List the organs, tissues, cells, and molecules involved in blood glucose regulation.
Explain the concept of negative feedback control and antagonistic regulation.
Outline the cellular fate of glucose.
BLOOD SUGAR REGULATION
Glucose and Energy
Sugar Sources (internal and external)
Other Substances Found in Blood
Normal Blood Sugar Ranges
The Pancreas (Islets of Langerhans)
Causes of Blood Sugar Fluctuations
Alpha Cells and Glucagon (acts on hepatocytes, glycogenolysis)
Side Note: Clinical Insights - Hypoglycemia
Beta Cells and Insulin (facilitates cellular uptake; glycogenesis)
Side Note: Clinical Insights - Hyperglycemia
Negative Feedback Control
Antagonistic Regulation Between Glucagon and Insulin
Other Regulator of Pancreatic Hormones
Popup: Human Growth Hormone
