Question

atp is critical to all cells. how does the structure of atp relate to the function of atp. what is the overall atp hydrolyzing and synthesizing reaction

Answer 1

ATP has a chain of three phosphates attached to an Adenosine in one end. Phosphate bonds are high-energy bonds (but stable though), which performs the job of energy transfer. The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached,and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP to ATP. This explains its ability to release energy quickly. As it is a relatively small molecule, it has a higher mobility.

ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy. ATP + H₂O ⇌ ADP+Pi+free energy

ATP synthase is a process that creates the energy storage molecule adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells for all organisms.The overall reaction catalyzed by ATP synthase is : ADP + P_i + 3H⁺_out ⇌ ATP+H₂O +3H
