second messenger cascade
Explanation:
Second messenger cascade is activated by the NE beta receptor which then activates the G protein. G protein in turn activates the enzyme responsible for converting ATP to cAMP i.e adenylyl cyclase.

The enzyme phospholipase is released as the G proteins get active and breaks down the phospholipid membrane into two secondary messenger molecule.

The lakes and the ponds are freshwater bodies of water. They can be formed in numerous different ways, from melting of glaciers, rivers flowing into closed valleys, changes in the geography of a space, increased amounts of precipitation. They can vary in size, and there are ponds and lakes that are very small, just few square meters, or to be thousands of square kilometers in size.

Some lakes can be very old, millions of years of age, like the Ohrid Lake in Macedonia, which is also the most important lake in the world from biogeographical stance of point, and it is considered as one of the most attractive ones in the world as well.
