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.
The oxidation of glucose begins during glycolysis. NAD+ accepts the electrons during the oxidation, and as a result it gets reduced. A total of 2 NADH are produced. Recall that NAD+ is a coenzyme (organic compound required by an enzyme for activity) that is used in redox reactions. Enzymes that catalyze redox reactions with the help of coenzymes such as NAD+ are called dehydrogenases. Pyruvic acid is a branch point. It still has much energy and can be further degraded. If oxygen is present (aerobic conditions) pyruvate is metabolized via cellular respiration (i.e., citric acid cycle and ETC. Without oxygen, anaerobic conditions, pyruvate is metabolized via fermentation.
