Every time you see the ATP starburst or lighting symbol you should relate to it which concept

The concept must be identified: that the energy currency for cells is ATP.

Explanation:

ATP is the abbreviation of the term Adenosine Triphosphate, the presence of its three phosphors and the dephosphorylation of them are the sources of chemical and electronic energy that our body and our cells need to be able to develop life.

The following reaction occurs in each ATP molecule used for energy purposes:

ATP + KINASE > ADP + P (inorganic)

Kinase is the enzyme that dephosphorylates the phosphorous molecules of ATP resulting in an ADP (adenosine diphosphate) and a free inorganic phosphorus.

b. the carbon cycle ensures living things have a source of hydrogen
