An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart 's electrical activity as line tracings on paper.The spikes and dips in the tracings are called waves.The heart is a muscular pump made up of four chambers.n electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart.

This process is an important step in the synthesis of some non-essential amino acids (amino acids that can be synthesized de novo by the organism). The chirality of an amino acid is determined during transamination. This reaction uses the coenzyme PLP, and has been shown to be a kinetically perfect reaction.
Coenzyme A is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it as a substrate. In humans, CoA biosynthesis requires cysteine, pantothenate, and adenosine triphosphate.
