Biodiversity is of great importance in order to maintain stable ecosystems. An ecosystem is a group of life forms that live together in a balanced and stable community. If there is a sudden change in that community’s environment, the balance of the community may change which may cause it to be destroyed.

The cyclin B–Cdc2 complex controls the passage from G2 into M and is assembled before mitosis however, its catalytic activity is

postnew [5]

Answer:

Phosphorylases that selectively add phosphate groups to the Cdc-2 subunit, thereby activating this complex.

Explanation:

The cyclin B-Cdc-2 (also known as maturation-promoting factor or simply MPF) complex is activated when it enters into the nucleus during the G2/M transition in the cell cycle. Cdc-2 is a protein kinase that associates with cyclin proteins. These proteins (cyclins) regulate the cell cycle by activating cyclin-dependent kinases. It is well known that phosphorylation of the Cdc2 subunit at different residues can both activate and inactivate the MPF complex. Moreover, enzymes capable of both inactivating phosphorylases and activating phosphatases have also shown to be able to activate MPF.
