Adenosince Triphosphate is broken down into one molecule of inorganic phosphate and a molecule of adenosine diphosphate, the energy released from this bond is captured and use to drive most cellular processes. some form of carbohydrate or triglyceride is used to generate the ATP in the first place depending upon a particular species and needs at the time
The main responsible for the delay among the atrial and
ventricular contractions is the action potential conduction velocity of the AV
node cells. If the atria and ventricles contract simultaneously, atria cannot
give any help in filling the ventricles, which is needed, especially in those
with stiff ventricles as in the elderly. Hence atria have to contract first and
then the ventricles.
