Carbohydrate Metabolism — Flashcards

Pyruvate is converted to _____ via the enzyme lactate dehydrogenase (LDH) (Cori cycle)

Glucose is converted to _____ by the enzyme hexokinase in most tissues

Pyruvate carboxylase requires _____, biotin, and CO2

When _____ glucose unit remains on a branch of glycogen, debranching enzyme (-1,6-glucosidase) cleaves off the last residue, liberating glucose

Pyruvate may be converted to _____ via the enzyme pyruvate carboxylase

_____ is converted to UDP-glucose via the enzyme UDP-glucose pyrophosphorylase (glycogen synthesis)

The branched glycogen molecule is cleaved by the enzyme _____ in the lysosomes only.

Gluconeogenesis occurs primarily in the _____, but necessary enzymes are also found in the kidney and intestinal epithelium

The byproducts of _____ fermentation are gases (CO2, H2) and short-chain fatty acids (e.g., acetate, propionate, butyrate).

Hint: aerobic or anaerobic

Glycogen synthase is stimulated by _____, cortisol, and glucose-6-phosphate
