The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon. [1] ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than ADP, while AMP contains one fewer phosphate group.
Mn 2+-dependent ADP-ribose/CDP-alcohol diphosphatase (EC 3.6.1.53, Mn2+-dependent ADP-ribose/CDP-alcohol pyrophosphatase, ADPRibase-Mn) is an enzyme with systematic name CDP-choline phosphohydrolase. [ 1 ] [ 2 ] This enzyme catalyses the following chemical reaction
ADP-ribose diphosphatase (EC 3.6.1.13) is an enzyme that catalyzes a hydrolysis reaction in which water nucleophilically attacks ADP-ribose to produce AMP and D-ribose 5-phosphate. Enzyme hydrolysis occurs by the breakage of a phosphoanhydride bond and is dependent on Mg 2+ ions that are held in complex by the enzyme.
3, to the relatively nontoxic excretion product urea. [6] This occurs at the cost of four "high-energy" phosphate bonds (3 ATP hydrolyzed to 2 ADP and one AMP). The conversion from ammonia to urea happens in five main steps. The first is needed for ammonia to enter the cycle and the following four are all a part of the cycle itself.

In fact, the thermodynamic efficiency is mostly lower in eukaryotic cells because ATP must be exported from the matrix to the cytoplasm, and ADP and phosphate must be imported from the cytoplasm. This "costs" one "extra" proton import per ATP, [ 6 ] [ 7 ] hence the actual efficiency is only 65% (= 2.4/3.67).

A mitochondrion (pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi.Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy.
