in isolated myocyte preparations the addition of the glycolytic inhibitor iodoacetate ( iaa , 5 mm ) and the mitochondrial inhibitor amytal ( 3 mm ) caused relaxed rod-shaped cells ( length/width ratio greater than 3:1 ) to contract into a stable population of square-shaped forms ( length/width ratio less than 3:1 ) , indicating an abrupt and severe decline in cellular atp levels .
