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

question 11

Multiple Choice

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
