Muscle acetyl group availability is a major determinant of oxygen deficit in humans during submaximal exercise

JA Timmons, T Gustafsson… - American Journal …, 1998 - journals.physiology.org
The delay in skeletal muscle mitochondrial ATP production at the onset of exercise is

[HTML][HTML] Protecting the cellular energy state during contractions: role of AMP deaminase

CR Hancock, JJ Brault, RL Terjung - J Physiol Pharmacol, 2006 - jpp.krakow.pl
AMP deaminase activity (AMP IMP+ NH 3) is the entry reaction to the purine nucleotide
cycle. In skeletal muscle, excessive energy demands during contractions leads to a net …
