Which of the following are correctly matched? a) compound fracture; the fractured bone ends penetrate the skinb) non-displaced fracture; the fractured bone ends are misalignedc) incomplete fracture; the bone is broken throughd) linear fracture; the break is perpendicular to the bone's long axis

The correct match is compound fracture: the fractured bone ends penetrate the skin. Letter A

Explanation:

A compound fracture, also known as open fracture, is a fracture in which there is an open wound or break in the skin near the site of the broken bone. Most often, this wound is caused by a fragment of bone breaking through the skin at the moment of the injury.

ATP releases energy stored within the molecule by the procedure known as ATP hydrolysis. In the hydrolysis of ATP, the energy gathered in the high-energy phosphoanhydride bonds in ATP gets discharged due to the dissociation of these bonds, like in muscles, where work is generated in the form of mechanical energy.  

The products formed in the process are inorganic phosphate and ADP. This ADP can get further dissociated to produce AMP and another orthophosphate.
