When a Cell "Burns" Food, Electrons Are Released from Chemical

When a cell "burns" food, electrons are released from chemical bonds in the food, and passed through an electron transport chain generating a proton gradient. As the protons pass through an ATPase the energy is used to generate ATP.
-Which of the following are examples of kinetic energy?

A) electrons in chemical bonds of the food molecules, proton gradients established, ATP molecules
B) protons moving through ATPase by facilitated diffusion, ATP molecules
C) electrons from food molecules moving through electron transport chain, proton gradients established
D) electrons from food molecules moving through the electron transport chain, and protons moving through ATPase
