Ethylene and cyanide induce a sharp increase in respiration in potato tubers (Solanum tuberosum, var. Russet) attended by changes in the glycolytic intermediates which indicate that both gases enhance glycolysis. The level of sucrose also increases in response to both treatments. The data are taken to indicate that both cyanide and ethylene either activate or affect the link between the conventional electron transport chain and the cyanide-insensitive path. It is further proposed that this activation may well be the primary event leading to the rise in respiration. Ethylene increases the level of adenosine 5'-triphosphate and it is suggested that because of the 4- to 6-fold increase in the rate of electron flux through site I, which continues to operate in the over-all cyanide-insensitive path, the absolute levels of adenosine 5'-triphosphate will also be expected to increase in the presence of cyanide. The increase in sucrose content is considered to be the consequence of the rise in adenosine 5'-triphosphate concentration.
乙烯和氰化物会使马铃薯块茎（马铃薯品种褐皮）的呼吸作用急剧增强，同时糖酵解中间产物发生变化，这表明这两种气体都会增强糖酵解。两种处理方式下，蔗糖水平也会升高。这些数据表明，氰化物和乙烯要么激活，要么影响传统电子传递链与氰化物不敏感途径之间的联系。进一步提出，这种激活很可能是导致呼吸作用增强的主要事件。乙烯会提高腺苷5'-三磷酸的水平，并且有人认为，由于通过位点I的电子通量速率增加了4至6倍，而位点I在整体氰化物不敏感途径中持续发挥作用，因此预计在存在氰化物的情况下，腺苷5'-三磷酸的绝对水平也会增加。蔗糖含量的增加被认为是腺苷5'-三磷酸浓度升高的结果。
