What is Mitochondria ?

A mitochondrion is a double-membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate, used as a source of chemical energy. They were first discovered by Albert von Kölliker in 1880 in the voluntary muscles of insects.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
