The correct answer is electrons.
Electron transport chain refers to an array of complexes, which mediates electrons from electron donors to electron acceptors through redox reactions, and combines the transfer of electrons with the transfer of protons through a membrane.
This produces an electrochemical proton gradient, which instigates the production of ATP. The ultimate electron acceptor in the electron transport chain is oxygen in aerobic respiration and sulfate in anaerobic respiration.
Since the temperature is above 37 degrees, the child’s digestive
system will begin to slow down as the enzyme begins to denature because both
the internal temperature and the external body heat influence digestive
processes. The effect upon the system of the temperature of food and drink is
also a matter of significant consideration.
