Answer:
The question lacks options, the options are:
A) By the linking of nucleic acids, the cell produces DNA.
B) By the addition of a phosphate group, ADP is converted to ATP.
C) By the linking of amino acids, the cell produces proteins.
D) By the removal of a phosphate group, ATP is converted to ADP.
The answer is D
Step-by-step explanation:
Adenosine triphosphate known as ATP is an energy carrying molecule found in the cells of all living organisms. It is the usable form of energy in living cells, produced when the cells of living organisms breakdown the chemical energy stored in organic foods.
ATP stores energy in its structure i.e. energy is stored when a phosphate group is added to Adenosine diphosphate (ADP) to become the popular ATP. This energy is released to be used in cellular activities when the phosphate group is removed from ATP to become ADP. This process of releasing the energy content of the ATP to another molecule to use as fuel is called PHOSPHORYLATION.
