Table 4. Respiratory rate in mitochondria isolated from MLs and MGs of heat-producing C. revoluta male cones

Oxygen uptake was measured as described in “Materials and Methods.” Data are means ± sd of at least five measurements. *P < 0.05 and **P < 0.005 as determined by Student’s t test.

Sequential Additions	Oxygen Uptake (nmol O₂ min⁻¹ mg⁻¹ protein)

ADP	67.87 ± 6.19	67.15 ± 21.72
KCN	30.84 ± 6.04	7.20 ± 1.38**
n-Propyl gallate	5.50 ± 3.39	1.99 ± 1.36
