<span>Summer temperatures in the Arctic remain cool, fluttering around zero in many places, from June through September. In fact, Arctic residents must frequently heat their homes all year long. Neighbourhoods near the sea tend to remain close to 0°C throughout the summer, but inland areas, particularly in the south, regularly reach 7°C–13°C, and hardly as much as 20°C.

In its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.
<h3>What is a kinase?</h3>
A kinase is an enzyme that catalyzes the addition of phosphate group and thus regulates cell signaling.
Moreover, phosphatases are enzyme that catalyze the removal of a phosphate group in a protein.
In conclusion, in its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.
