Answer:
When ATP is broken down to ADP
Explanation:
Energy is released from a molecule of ATP when the substance is broken down to ADP
ATP is the energy currency of a cell. It is called Adenosine Triphosphate
When a phosphate is removed, it become ADP - Adenosine Disphosphate.
In like manner, the breaking down releases inherent chemical energy and converts it to other forms of energy.
This is how the body system derives sufficient amount of energy for every of its activities.
When an organism undergoes cellular respiration, this is the process that is in play to release energy needed for the body to function
The light will enter they eye and it will be refracted as it
passes through the cornea. It will then pass the pupil which is controlled by
iris and will be further refracted by the lens. The cornea and lens together
will form a compound lens in order to project images which are inverted into the
retina.
Prostaglandin similarity with hormones is in the effect they achieve by binding to the receptors. Their effects are mediated by paracrine or autocrine mechanisms. Another hormone characteristic is the ability to stimulate adenylate cyclase activity, producing cAMP as the second messenger.

On the other hand, prostaglandins differ from hormones in that they are not produced at a specific place but in many different places throughout the body. Also, the metabolic degradation of prostaglandins is very rapid.</span>
