When atp is used by a cell to provide the energy for cellular work, the usual end products left over from the atp molecule are ADP

Explanation:

Like every other living thing that needs energy to survive the cells also needs energy for the proper functioning of the organism. Through Cellular respiration the cells derive energy in the form of ATP molecules.  

Adenosine triphosphate (ATP) releases energy to the required cell by transferring one phosphate and then becoming Adenosine diposphate (ADP).

Then after it releases energy it is all set up to absorb another phosphate molecule to become ATP. And this is the simple process of acquiring and transferring energy to the cells.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
