Dephosphorylation is the removal of a phosphate group from an organic molecule. This process is crucial in regulating cellular activities and signaling pathways.
5 Must Know Facts For Your Next Test
Dephosphorylation is often catalyzed by enzymes known as phosphatases.
It plays a key role in turning off signal transduction pathways by deactivating proteins.
Dephosphorylation can occur in various cellular locations, including the cytoplasm and mitochondria.
In the context of cellular respiration, dephosphorylation helps regulate metabolic pathways such as glycolysis and the citric acid cycle.
ATP (adenosine triphosphate) can be dephosphorylated to ADP (adenosine diphosphate), releasing energy for cellular functions.
