Multiple Choice
Blood sugar is regulated by two pancreatic hormones, namely insulin and glucagon. When blood sugar rises, insulin is released; it binds to receptors and, through signal transduction, results in an increase in glucose uptake by cells, effectively lowering blood glucose. When blood sugar decreases, glucagon is released, binds to cell receptors, and causes glucose to be released into circulation. Diabetes mellitus is a disorder that results from excessively high levels of blood glucose. Type II diabetics have normal to elevated levels of insulin. What, then, might be causing the elevated blood glucose levels?
A) defective receptors
B) inadequate insulin production
C) defective second messenger
D) inability to regulate gene expression
