Fig 3. Ratio of oxidative phosphorylation capacity (P) to electron transfer system capacity (E) in Non-raced and Raced Alaskan Huskies when FAO and NADH-linked substrates are provided (SUIT1).

The P/E ratio in the Raced is significantly greater than Non-raced dogs in SUIT1, indicating a closer matching of the capacity of the phosphorylation system with ETS capacity. N = 5 (Non-raced) and 6 (Raced). *p<0.05.
