Hepatic fuel metabolism during muscular work: role and regulation

Wasserman, D. H., Cherrington, A. D.·1991·American Journal of Physiology-Endocrinology and Metabolism

Abstract

The increased fuel demands of the working muscle necessitate that metabolic processes within the liver be accelerated accordingly. The sum of changes in hepatic glycogenolysis and gluconeogenesis are closely coupled to the increase in glucose uptake by the working muscle, due to the actions of the pancreatic hormones. The exercise-induced rise in glucagon and fall in insulin interact to stimulate hepatic glycogenolysis, whereas the increase in gluconeogenesis is determined primarily by glucagon action. The increment in gluconeogenesis is caused by increases in hepatic gluconeogenic precursor delivery and fractional extraction as well as in the efficiency of intrahepatic conversion to glucose. Glucagon stimulates the latter two processes. Epinephrine may become important in the regulation of hepatic glucose production during prolonged or heavy exercise when its levels are particularly high. On the other hand, there is no evidence that hepatic innervation is essential for the rise in hepatic glucose production during exercise. Nonesterified fatty acid (NEFA) delivery to, uptake of, and oxidation by the liver are accelerated during prolonged exercise, resulting in an increase in ketogenesis. The rate of the first two of these processes is largely determined by factors that stimulate fat mobilization. The third step is regulated by both NEFA delivery to and glucagon-stimulated fat oxidation within the liver. The increase in hepatic fat oxidation produces energy that fuels glucone…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
