Schematic presentation of energy flow at the AM* complex. (A) Energy flow during sliding movement. The molecular mechanism borrows energy from the environment and converts it into gross work. (B) Energy flow after the end of the ATPase lifetime. The energy supplied by ATP hydrolysis is released into the environment as heat. The borrowed energy is covered by part of the released energy. The energy used to maintain the high-energy state of the myosin head is released as heat into the environment.
