Arrhythmia Definition. A heart arrhythmia is an irregular heart beat: the beat may be too fast, too slow, or the rhythm may be irregular. Types. Arrhythmias can be classified by their origin (atria or ventricles) and by heart rate. Tachycardia. A fast (over 100 beats per minute) heart rate is called tachycardia.
What are products of the light and dark reactions of photosynthesis? The products of the light reaction are 602, 12 NADPH2 and 18 ATP.    The products of the dark reaction are C6H12O6, 12 NADP, 18 ADP, 18 Phosphates and 6H2O.
During the process of photosynthesis, we obtain, C6H12O6 (glucose) as the main product and oxygen as the byproduct. This process has two reactions: light reaction and dark reaction. In light reaction water is broken down and; hydrogen, protons, electrons, assimilatory powers(ATP and NADPH) are produced and oxygen is evolved.
