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.
Acetyl-CoA, main product of the Pyruvate Dehydrogenase Complex in aerobic respiration, starts the Krebs cycle. (An irreversible reaction that is link between glycolysis and the citric acid cycle.) The mechanism of the synthesis of acetyl coenzyme A from pyruvate requires five coenzymes and three enzymes.yruvate + CoA + NAD + â acetyl CoA + CO 2 + NADH + H +. This is an irreversible reaction which links glycolysis and the citric acid cycle together. As shown, CO 2 is produced by pyruvate dehydrogenase complex and it captures high-transfer-potential electrons in the form of NADH.
