Spontaneous and non-phosphorylating respiratory rates in wild type and mutant cells.

Strains	JO2	JO2-non phosphorylating	Ratio
S. c – WT	70 (± 4.5)	27 (± 0.8)****	2.59 (± 0.2)
S. c – Δhxk2	91 (± 2.4)	36 (± 1.9)****	2.57 (± 0.4)
S. c – Δhap4↑	122 (± 5.3)	50 (± 0.4)****	2.52 (± 0.2)
S. c – Δhxk2hap4↑	192 (± 6.5)	73 (± 4.2)****	2.61 (± 0.2)
C. u	498 (± 14.6)	ND	ND

Respiratory rates were assessed after 8-h incubation in the presence of glucose. Non-phosphorylating respiratory rate was determined in the presence of 0.1 mM Triethyltin, an inhibitor of mitochondrial ATPsynthase.

ND, not determined.
