Skeletal muscles account for approximately 43% of the typical body mass. At rest, they use about 18% of the BMR. Of the total energy burned by the skeletal muscle, only 25% is used for work, and this is the muscular efficiency. What happens to the remaining 75% of energy? Choose the best answer. It is reabsorbed and stored for later use. It is transferred as electrical energy from the muscle to muscle. It is converted to heat to warm the body. It is used to make more ATP.
