Questions and Answers

Which hormone acts to lower blood glucose levels?

  • Glucose
  • Glycogen
  • Insulin (correct)
  • Glucagon

    • What is the role of the liver in carbohydrate metabolism?

  • Enhancing glucose transport into skeletal muscle, adipose tissue, and the heart
  • Producing and secreting digestive enzymes
  • Secreting insulin and glucagon to regulate blood glucose levels
  • Balancing the uptake and storage of glucose via glycogenesis and the release of glucose via glycogenolysis and gluconeogenesis (correct)

    • Where is insulin secreted from?

  • Skeletal muscle cells
  • Liver cells
  • 𝛼 cells of islets of Langerhans from the pancreas
  • 𝛽 cells of islets of Langerhans from the pancreas (correct)
