Fig. 3. Glycogen synthesis and palmitate oxidation during glycogenesis in muscle slices from exercised fish. (A) Muscle glycogen levels in tissue sampled immediately after exercise (Time 0) and in tissue incubated for 60 min in the substrates indicated. (B) The incorporation of ¹⁴C from palmitate into CO₂ produced. All values are given in nmol g wet mass^–1 to facilitate comparisons between components. Data are presented as the mean ± 1 s.e.m. for slices from eight different fish (N=8). Columns within the same panel with the same letter are not significantly different from one another.
