Question

(I NEED HELP ASAP!!!!)

Sheila eats an energy bar right before she goes on a run.What energy changes will occur in Sheila as she runs after eating?

Answer 1

Chemical (in the form of energy) to mechanical (potential and kinetic) to heat

Answer 2

The correct answer would be "chemical energy is converted into mechanical energy".

The chemical energy present in the food (energy bar in this case) is converted into ATP (adenosine triphosphate, the energy currency of the cell) by the process of the cellular respiration.

The ATP is then used by skeletal muscles to produce movement and thus, the chemical energy is ultimately converted into mechanical energy.
