A woman runs as shown. What main energy conversion occurs?

Answer 1

When a woman runs, the main energy conversion that occurs is the transformation of chemical energy from the food she has consumed into kinetic energy, which enables her to move. As her muscles contract, they convert stored chemical energy in the form of ATP (adenosine triphosphate) into mechanical energy, allowing her to propel herself forward. Additionally, there is some conversion of chemical energy into thermal energy (heat) due to metabolic processes and muscle activity.
