ATP is short for adenosine triphosphate, which means that there is an adenosine molecule (A) (don't worry too much about that for the moment) with three phosphates (P) joined onto it. ATP could be written at APPP. ADP stands for adenosine diphosphate, which means the A has 2 phosphates joined to it, and might look like APP.
Therefore,
APPP -> APP + P
ATP can become ADP plus a free P (because one broke off)

Answer:
Muscles contract through a chain process of electrochemical signalling between the nervous system and muscles.
Explanation:
The muscle contraction is initiated by the nervous system by sending a signal. This signal also referred to as action potential travel through the motor neuron. This motor neuron releases a chemical signal to muscle when the electrical signal carried by it reaches the neuromuscular junction (a junction where motor neuron meets the muscles).
The chemical message referred to as neurotransmitter binds to the receptors present on the muscle fibers. These receptors causes the influx of sodium ion which in turn trigger the release of calcium ion thereby initiating the contraction of muscles.
