Very nice figure showing the fiber type composition of hindlimb muscles in mice. Notice the very high proportion of type IIb fibers in most muscles, a fiber type that does not exist in humans.
Wow, this is simply fascinating!

The human egg - the oocyte - does not have mitochondrial complex I, one of the most critical energy-transforming mitochondrial feature in the human brain
"Complex I is neither assembled nor active in early oocytes"

@PGreenhaff @MViggars I would not rule out an influence but the paper noted that the diurnal effect on respiration required Sirt4, which implicates changes in acetylation status of mitochondrial proteins in the effect. So to me the question is what would regulate Sirt4 in a diurnal manner?
