Respiration is a process for many chemical bonds inside the body break and release energy this energy is used to perform various activities such as moving muscles. explain the energy transformation in this process30 ! (a) chemical energy from broken bonds is transformed into mechanical energy for muscles (b) mechanical energy from broken bones is transformed into chemical energy for muscles (c) mechanical energy from broken bones is transformed into electrical energy for muscles (d) heat energy from broken bones and transformed into electrical energy for muscles
