... functioning of muscle proteins involved in calcium cycling to mediate contraction and relaxation ( Berchtold et al., 2000 ; Allen et al., 2008 ; Bruton et al., 2010 ). Theory predicts that voluntary speed reflects minimisation of the cost of transport (i.e. the energy used for a given distance travelled...

...) in muscle. However, UV-B did not affect the activity of sarco-endoplasmic reticulum ATPase (SERCA), an enzyme associated with muscle calcium cycling and muscle relaxation. UV-B did not affect ADP phosphorylation (state 3) rates of mitochondrial respiration, and it did not alter the amount of ATP produced...
