Recall that all bonds require energy to break, but energy is released when bonds are formed. With this in mind, explain why it is incorrect to say that the phosphoester bond in ATP releases a large amount of energy when ATP turns into ADP?

Explanation:

This is incorrect because the energy is released when water molecules are added to the ends of ADP and phosphate pieces

Adenosine triphosphate in short called ATP is a nucleoside triphosphate which is used in cells as a coenzyme and is often called the "molecular unit of currency" of intracellular energy transfer

Each of the phosphorous atoms are highly electrophilic and can react with nucleophiles like the OH of water

The large negative ΔGo for the hydrolysis of one of the phosphoanhydride bonds can be attributed to a relative destabilization of the reactants (ATP and water) and relative stabilization of the products (ADP = Pi)

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
