Implication

ATP hydrolysis confined to contraction in frog muscle; leaves open energy use during relaxation in mammalian myocardium.

Population

fluorodinitrobenzene (FDNB)-treated frog sartorius muscle

Intervention

0.2 sec tetanus at 0 degrees C

Comparator

muscles interrupted at the height of contraction versus those that have also relaxed

Outcome

breakdown of ATP and formation of ADP, AMP, and phosphatesurrogate

This study demonstrates that all ATP breakdown in the frog sartorius muscle occurs during the contraction phase, with no additional metabolism during relaxation.
