Accordingly, Bekhit and Faustman [5] suggested that the principal chemical ingredient that affects meat color was myoglobin from sarcoplasm.
The increased concentration of free calcium in sarcoplasm augments the contraction force of the myocardium and the positive inotropic effect (JOUBERT, 1989).
Sarcoplasmic Reticulum: Smooth endoplasmic reticulum found in muscle cells that regulates the calcium ion concentration in the cytoplasm of striated muscle cells; stores calcium ions and pumps them into sarcoplasm when the muscle fiber is stimulated, thereby playing a major role in muscle contraction.
These are dependent on ATP and Ca+2 in the sarcoplasm which are sufficient in diabetic muscle for a single twitch.
2001) reported damage of the muscle triads system (T-tubule and terminal cisternae of the sarcoplasmic reticulum) after downhill running in rats that probably disturbed the link between excitation of the sarcolemma and calcium release to the sarcoplasm (Prasartwuth et al.
2+] stored in the sarcoplasmic reticulum into the sarcoplasm causing an increase in cytosolic levels inducing vasoconstriction of coronary arteries [121].
We observed the colocalization of MAO-A and MAO-B in the sarcoplasm of cardiomyocytes, fibroblasts, endothelial cells, and mesothelial cells, and the absence of the immunostaining in the collagen fibers of the connective tissue (Figure 6(a)).
When the muscle temperature is reduced (15[degrees]C) before rigor mortis, the sarcoplasmic reticulum does not work effectively and cannot bind to calcium, which leads to an abundance of calcium in the sarcoplasm.
mPTP formation creates a non-selective channel between the inner mitochondrial membrane and the sarcoplasm.
