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
Which metabolic enzymes require an obligate activator? 1. _____2. Carbamoyl phosphate synthetase I (N-acetylglutamate)
#4
_____ reactions are chemical reactions that form intermediates of a metabolic pathway.
#5
Glucagon causes _____ fatty acid synthesis and increased lipolysis, which shunts substrates towards gluconeogenesis
#6
_____ deficiency causes a buildup of pyruvate that gets shunted to lactate (via LDH) and alanine (via ALT)
#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
Increased NADH/NAD+ (e.g. due to ethanol) causes increased conversion of _____ -> malate, thus preventing gluconeogenesis
