Succinate acts as an oxygen sensor in the cell and can help turn on specific pathways that stimulate cells to grow in a low-oxygen environment (hypoxia). (medlineplus.gov)
Chronic oxygen deficiency (hypoxia) in cells with two mutated copies of the FH gene may encourage tumor formation and result in the tendency to develop leiomyomas and renal cell cancer. (medlineplus.gov)

However, there are organism that will undergo fermentation even when the oxygen is present are called as facultative anaerobes. (researchtweet.com)

Most of the body's catabolic pathways converge on the TCA cycle, as the diagram shows. (citizendium.org)
Among these, the citric acid cycle intermediate succinate stands out owing to its multiple roles in disparate pathways, its dramatic concentration changes and its selective cell release. (nature.com)
