If these enzymes are not present or functional then the reactions will not occur, so the breakdown of glucose is controlled ... greater quantity of ATP. A pyruvate molecule enters the mitochondria ...

The researchers identified the structure of this machine, the mitochondrial pyruvate carrier (MPC), and 50 years since its discovery, have shown how it operates like the lock on a canal to transport ...

Known as the mitochondrial pyruvate carrier, this molecular machine was first proposed to exist in 1971, but it has taken until now for scientists to visualise its structure at the atomic scale ...
