A: The corneal reflex is an involuntary closing of the eyelids when the cornea is touched by a foreign object. The function of this reflex is to protect the eye from damage. Absence of a corneal reflex may indicate damage to the fifth and seventh cranial nerves, which mediate the reflex.
Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
Cellular Respiration. Cellular respiration is a process through which the body releases energy stored in glucose, which is a compound composed of carbon, hydrogen and oxygen. That energy is used to produce adenosine triphosphate, or ADP, which scientists call the energy currency of the cell.During respiration, the body oxidizes glucose and energy is released. The oxygen in the compound is reduced to water, while the carbon atoms in the glucose are released as carbon dioxide.uring respiration, the body oxidizes glucose and energy is released.
