Which is correct about energy changes in living cells ?

Potential energy function is the energy possessed by the body by virtue of its position. Potential energy of a body is the energy possessed by the body by virtue of its velocity and is given by 1//2 mv^(2) . Energy can neither be created nor be destroyed. However, energy can be changed from one form to the other, such that energy appearing in one form to the other, such that energy appearing in one form is equal to the energy disappearing in the other form. Kinetic energy of the body 5 s after it starts falling is

Choose the correct options – (1) )The work done by forces may be equal to change in kinetic energy (2)The work done by forces may be equal to change in potential energy (3) The work done by forces may be equal to change in total energy (4) The work done by forces must be equal to change in potential energy.
