2. The Ca2+ ATPase pumps on the sarcoplasmic reticulum membrane play an important role in muscle contraction. In patients with muscular dystrophy, there is some evidence that shows the expression of the Ca2+ ATPase pumps is diminished (there are fewer). Which of the following cellular effects may be a result of the diminished number of Ca2+ ATPase pumps? A)Reduced Ca2+ release through the RyR B)Reduced Ca2+ uptake into the SR C)Slowed activity of the Na/K pump D)Reduced communication between the DHP receptor and the Ca2+ ATPase pumps E)Reduced communication between the DHP Receptor and the Ryanodine receptor
