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
<u>Explanation:</u>
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 are the theories of evolution ?
it is the same question .
Explanation: In biology it refers to absorb changes in organisms , to there descent from a common from a common ancestor , and at a technical level to a change in gene frequency over time , it can also refer to explanatory theories [ such as charles darwin 's theory of natural selection ] which explain the machanism's of evolution .
