10 Questions
Which hormone acts to lower blood glucose levels?
Insulin
What is the role of the liver in carbohydrate metabolism?
Balancing the uptake and storage of glucose via glycogenesis and the release of glucose via glycogenolysis and gluconeogenesis
Where is insulin secreted from?
𝛽 cells of islets of Langerhans from the pancreas
When is glucagon secreted?
When there is a fall in blood glucose level from the normal range
What is the primary function of glucagon?
To raise blood glucose levels
Match the following organs with their roles in carbohydrate metabolism:
Liver = Release of glucose via glycogenolysis and gluconeogenesis Pancreas = Endocrine function in regulating blood glucose levels
Match the following hormones with their effects on blood glucose levels:
Insulin = Enhances glucose transport into skeletal muscle, adipose tissue, and the heart Glucagon = Secreted when there is a fall in blood glucose level from the normal range
Match the following functions with the respective hormones:
Insulin = Increasing glycogenesis, lipogenesis, and glycolysis Glucagon = Secretion when there is a fall in blood glucose level from the normal range
Match the following hormone-secreting cells with their secreted hormones:
𝛽 cells of islets of Langerhans from the pancreas = Responsible for enhanced glucose transport into tissues 𝛼 cells of islets of Langerhans from the pancreas = Secreted when there is a fall in blood glucose level from the normal range
Match the following terms with their descriptions:
Glycogenesis = Process of storing glucose as glycogen Glycogenolysis = Process of releasing glucose from glycogen Gluconeogenesis = Process of synthesizing new glucose from non-carbohydrate sources Hypoglycemic agents = Hormones that decrease glucose levels
Learn about the regulation of carbohydrate metabolism in the liver and pancreas, and understand the processes of glycogenesis, glycogenolysis, and gluconeogenesis. Explore the central role of the liver in balancing glucose uptake and storage, as well as the dual endocrine and exocrine functions of the pancreas.
