... plants, and then quantified gene expression of Troponin t ( Tnt ) and flight muscle metabolism of the adult insects. Differences in Tnt spliceform ratios in insect flight muscles correlate with changes to flight muscle metabolism and flight muscle output. We found that SAW adults reared on induced def1...

... (lipid-based metabolism) capabilities higher than would be predicted from the allometric perspective of its extreme body size. Relationships between muscle metabolism and body mass were fibre-type specific. The ‘sprinter’ profile of the fin whale swimming muscle, particularly of its superficial...

... the relationship between these parameters varies greatly with physiological state. Quantifying fuel kinetics directly is therefore crucial to the understanding of muscle metabolism. This review focuses on how carbohydrates, lipids and amino acids are provided to fish muscles during hypoxia and swimming. Both...

... of the intracellular lactate shuttle and glycogen shunt models. Muscle metabolism Lactate bioenergetics Hyperpolarized 13 C Pyruvate Biologists often view lactate as a hypoxia indicator and a dead-end product of glycolysis, which muscle must export to liver for clearance in the Cori cycle ( Brooks et...

... (†) by lactate or glucose (P<0.05,one-way ANOVA, Fisher's PLSD, N=4–11). Warm acclimation and incubation results in an increased conversion of glucose to lactate and increased glycogen synthesis from lactate (P<0.05). Cold-acclimated muscles metabolized 30× more lactate than glucose, a factor 3...

... . These results reveal a very close match between predicted and measured PGI flux capacities, and support the concept of an economical design of muscle metabolism in systems working at very high metabolic rates. References Balderrama , N. M. , Almeida , B. L. O. and Nunez , J. A. ( 1992...
