In cellular respiration, the chemical energy stored in organic molecules is converted to chemical energy in ATP. However, some of the chemical energy from organic molecules can be diverted to heat by organisms that use it for thermoregulation. Which of the following changes occurs during cellular respiration to divert energy from ATP production to heat production?

A. Oxidative phosphorylation is uncoupled from electron transport.
B. The rate of glycolysis is increased.
C. Oxygen is removed as the final acceptor of the electron transport
chain.
D. The energy levels of electrons are decreased along the electron
transport chain.
