blase pattern of a cell - Essay ExampleThe cardiac myocyte is an extremely active cell and it contracts adept to three times in one second. This contractility is far greater than the contraction of the skeletal muscle. Owing to this, the cardiac myocyte requires a large amount of energy in the form of adenosine triphosphate. The high metabolism of the cardiac myocyte is the modestness why these cells possess an extensive amount of mitochondria. Furthermore, the cardiac myocyte also cannot generate ATP without oxygen. It meets its demand of generating ATP oxidatively by utilizing different energy sources which include fatty acids, lactate and glucose (Klabunde 2005). The cardiac myocyte has the capability of altering its go bad of contraction as per the requirements of the human body. Its contractility varies throughout the different times of the day according to the needs of the body. other important feature of the cardiac myocyte is that this cell does not have the capability o f undergoing mitosis and the cells do not add in number. But when there is a greater load, the cardiac myocyte undergoes the process of hypertrophy to compensate for the increase work load (Abel & Wilkins 2004 Hill & Olsen 2012 Walker & Spinale 2006).The cardiac myocyte exhibits varying functions over the 24 hour interval. During the effect of sleep, the cardiac myocyte maintains decreased contraction and the metabolic needs of the cardiac myocytes are also low. This is owing to the concomitant that the body is not in need of an increased blood supply and is in a resting state. The major(ip) factor which is responsible in the maintenance of the changing functions of the cardiac myocyte is the atomic number 20 ions. During the hours of sleep, the entry and the exit of the calcium ions in the cardiac myocyte are very low. This is the main reason why the cardiac myocyte retains slow contractions (Hill and Olson 2012).When an psyche wakes up, the cardiac myocyte starts functioning at a faster pace. An important research has
