As it might be possible that the glycolytic enzymes were only attached to the surface of the mitochondria, as for instance in the case of hexokinase which is attached to the voltage-dependent anion channel (VDAC) in tumours (Lunt and Vander Heiden 2011), we tested the latency of enzymatic activities in the presence or absence of Triton X-100. The gene discussed is VDAC1; the disease is neoplasm.
