2. Glucagon release is stimulated by which physiologic factor?
a. Increases in ci rculating insulin that is secreted
b. Decreases in blood amino acids
, c. Stimulation of the sympathetic nervous system
d. High blood glucose levels

3. The patient has been admitted from a skilled nursing facilit y with urinary
sepsis and has severe muscle wasting. What is the process by which fat
and protein are converted to glucose for fuel?
a. Gl ycogenol ysis
b. Gluconeogenesis
c. Digestion
d. Biotransformation
ANS: B
For long-term energy needs, glucagon stimulates glucose release
through the more complex process of gluconeogenesis. In
gluconeogenesis, fat and protein nutrients are rapidl y broken down into
end products that are then changed into glucose.
