Crabtree effect
Description
The Crabtree effect describes the observation that respiration is frequently inhibited when high concentrations of glucose or fructose are added to the culture medium - a phenomenon observed in numerous cell types, particularly in proliferating cells, not only in tumor cells, in bacteria, and yeast. The Pasteur effect (suppression of glycolysis by oygen) is the converse of the Crabtree effect (aerobic glycolysis to lactate or ethanol).

Crabtree (1929)
- Introduction: 'Warburg has suggested several generalisations, showing characteristic relationships between the magnitudes of the respiration and the aerobic and anaerobic glycolysis. The constant result which emerged was the abnormally high value of the anaerobic glycolysis as compared with the respiration. Assuming that the oxygen utilised was functioning at its maximum efficiency in causing the removal or non-formation of lactic acid under aerobic conditions, the respiration was found inadequate to check the glycolysis completely, a relatively large excess fermentation remaining. ...
- Summary: 'The general result of these observations is to emphasise the difficulty of including the wide variations found in the carbohydrate metabolism of tumour tissue in one generalisation. The constant factor is the possession of a high aerobic glycolysis, which, though not specific for tumour tissue, is a source of energy available for uncontrolled proliferation.'
