Question

Walking converts what type of energy into mechanical energy?

Answer 1

The answer is chemical energy. 

In our body, our chemical energy comes in the form of glucose. It is glucose that is turned into mechanical energy in our body. When we move, our muscles act as a transducer. As muscles contract, they convert the glucose in our body into mechanical energy. The mechanical energy in our muscles is also called muscular energy. 

Answer 2

The correct answer is chemical energy. Walking converts into a chemical energy which is a type of mechanical energy. Chemical energy is the energy stored in the chemical compound bonds and mostly released by the chemical reaction which will produce heat.
