Glucagon acts on the _____ (primarily) and adipose tissue
#2
After three days of starvation, the main source of energy for the brain becomes _____ from adipose stores
#3
Urea cycle and Krebs cycle are linked at _____
#4
Increased glucagon (fasting) leads to increased cAMP and protein kinase A, thus _____ activity of FBPase-2 and decreasing activity of PFK-2
#5
In starvation, the enzyme 5'-deiodinase is _____ in tissues such as skeletal muscle, but not inhibited in the other tissues, such as the brain
#6
In a person starving for more than 18 hours, the source of energy is _____.
#7
Effect of diabetes on hepatic glycolysis: no answer _____
- No PFK-2 due to lack of insulin
- No glucose trapping in liver leads to elevated blood glucose (hyperglycemia)
#8
Glucagon causes _____ fatty acid synthesis and increased lipolysis, which shunts substrates towards gluconeogenesis
#9
Increased NADH/NAD+ (e.g. due to ethanol) causes increased conversion of _____ -> malate, thus preventing gluconeogenesis
