Size- and age-dependent changes in adductor muscle swimming physiology of the scallop Aequipecten opercularis.
The decline of cellular and especially mitochondrial functions with age is, among other causes, held responsible for a decrease in physiological fitness and exercise capacity during lifetime. We investigated size- and age-related changes in the physiology of exercising specimens of the short lived swimming scallop Aequipecten opercularis (maximum life span 8 to 10 years) from the Isle of Man, U...
متن کاملContractile properties of the striated adductor muscle in the bay scallop Argopecten irradians at several temperatures.
The isometric and isotonic contractile properties of the cross-striated adductor muscle of the bay scallop (Argopecten irradians) were measured in vitro at 10, 15 and 20 degrees C. The length at which twitch force was maximal as a function of the closed length in situ (L0/Lcl) averaged 1.38 +/- 0.01 (mean +/- S.E.M.) at 10 degrees C. This length is very close to the typical length at maximum ga...
متن کاملPower output of scallop adductor muscle during contractions replicating the in vivo mechanical cycle.
Because measurements on isolated skeletal muscles are often made with limited knowledge of in vivo kinematics, predictions of mechanical performance during natural movements are subject to considerable uncertainties. We used information on the in vivo length cycle and phase of activation of the scallop adductor during swimming at 10 degrees C to design an in vitro contractile regime that replic...
متن کاملAmino acid sequence of troponin C from scallop striated adductor muscle.
Troponin and its Ca(2+)-binding subunit troponin C (TnC) of the Ezo-giant scallop, Patinopecten yessoensis, have been revealed to bind only 1 mol of Ca2+/mol irrespective of the presence and absence of Mg2+. The amino acid sequence of the TnC has been determined by the automated Edman degradation. TnC is composed of 152 residues including 3 tryptophans at positions 53, 70, and 109, 4 cysteines ...
متن کاملControl of D-octopine formation in scallop adductor muscle as revealed through thermodynamic studies of octopine dehydrogenase.
Octopine dehydrogenase (OcDH) from the adductor muscle of the great scallop, Pecten maximus (Linné, 1758), catalyses the NADH-dependent condensation of l-arginine and pyruvate to d-octopine, NAD(+) and water during escape swimming and subsequent recovery. During exercise, ATP is mainly provided by the transphosphorylation of phospho-l-arginine and to some extent by anaerobic glycolysis. NADH re...
