Question
_____ If glycogen stores in a muscle fiber are markedly depleted prior to slaughter a) rigor mortis is associated with a markedly decreased pH b) increased concentrations of sodium lactate accumulate in the tissue c) post mortem changes in tenderness are not affected d) muscle tissue is comparatively dry and sticky.
_____ A slow oxidative (type I) muscle fiber would a) have a low myoglobin content b) have a high myoglobin content c) have a low resistance to fatigue d) have a high glycogen content e) two of the above are correct.
Explanation / Answer
a) rigor mortis is associated with a markedly decreased pH
The tissue will be more firm and dry, with a lower pH due to the lactic acid produced during the oxidation of glycogen
b) have a high myoglobin content
High myoglobin allows fast delivery of oxygen to the mitochondria of these tissues.
