"VO2=5.86X10^-8+1.42X10^-7U (eq.2) [where VO2=rate of oxygen uptake and U=swimming speed] Because the standard metabolic rate (SMR) is defined as the energy spent independent of locomotion (Hill et al., 2004), it can be estimated to be VO2 at a zero swimming speed. The linear regression of VO2 vs U gives us a primary approximation of SMR of a single Paramecium cell as 1.18X10^–6J/h by extrapolating VO2 down to U=0 and equating 1 liter of oxygen with 20.1 kJ (Schmidt-Nielsen,
1984)." Note-at U=0 eq.2 gives VO2=1.18X10^-6kJ/h rather than 1.18X10^-6J/h |
