This produces one molecule of ATP from ADP. | Pyruvate translocasePyruvate translocase is a protein that transports selectively pyruvate across the inner membrane of the mitochondrion. |
| Pyramidal numberA pyramidal number is one of several kinds of numbers: Triangular pyramidal number Square pyramidal number Pentagonal pyramidal number Heptagonal pyramidal number. | Pyruvate dehydrogenasePyruvate dehydrogenase is an allosteric enzyme that transforms pyruvate into acetyl-CoA which is then used in the citric acid cycle. It is inhibited when either of the three following ratios are increased: [ATP]/[ADP], [NADH]/[NAD+] and [acetyl-CoA]/[CoAS | Pyrenean ShepherdThe Pyrenean Shepherd is a medium-small dog that was bred originally in the 1700s for herding.
