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.
Pyruvate, generated in muscle and other peripheral tissues, can be transaminated to alanine which is returned to the liver for gluconeogenesis. The transamination reaction requires an Î±-amino acid as donor of the amino group, generating an Î±-keto acid in the process. This pathway is termed the glucose-alanine cycle.
