Succinyl coa to succinate reaction
WebIn parasites, acetate is produced from acetyl-CoA by two different reactions, both involving substrate level phosphorylation, that are catalysed by either a cytosolic acetyl-CoA synthetase (ACS) or an organellar acetate:succinate CoA-transferase (ASCT). The ACS reaction is directly coupled to ATP synthesis, whereas the ASCT reaction yields ... WebThe reverse reaction generates succinyl-CoA from succinate to fuel ketone body and heme synthesis. [8] [10] While SCS is ubiquitously expressed, SUCLA2 is predominantly expressed in catabolic tissues reliant on ATP as their main energy source, including heart, brain, and skeletal muscle.
