“…ATP concentrations within red and white skeletal muscle fibers from vertebrates (see Refs. 6,11,27,36,56,72,119,146,157,160,164,177,182,200,202,207,219,243,256,265,269,293,294,308). For mammals, red vs. white [CP], P = 0.0006 (two-tailed t test); for all vertebrates combined, red versus white [CP], P = 0.0085 (two-tailed t test).…”
