Animals heterozygous for ATPalpha alleles have reduced respiration. Respiration was measured from the emergent carbon dioxide from individual ATPalpha mutants and age-matched wild-type controls. ATPalpha mutants uniformly have significantly lower metabolic rates than controls. Error is SEM, n = 4–10, per genotype. Animals were 5–6 days old adults. Statistical significance was determined by Student’s t test (* P < 0.05, ** P < 0.01, and *** P < 0.001)
