Abstract: The importance of this computerized simulation study was to gain an understanding of the processes that account for the movement of substances across the plasma membrane‚ and to indicate the driving force for each. This may also be applied to the study of transport mechanisms in living membrane-bounded cells. Also‚ understanding of which way substances will move passively through a deferentially permeable membrane depending on the concentration differences. We used PhysioEx software to

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members

Diabetic ketoacidosis is an acute complication of diabetes that often occurs as a result of insulin deficiency in a person. Acute insulin deficiency in type I in diabetes mellitus‚ uncontrolled type I diabetes‚ medications such and corticosteroids‚ and a person’s poor compliance with their insulin injections or insulin pump failure are some of the causes of DKA. Diabetic ketoacidosis‚ most often occurs in those with type I diabetes‚ and is associated with hyperglycemia‚ ketosis‚ and metabolic acidosis

the cell and the entire body. To further understand these mechanisms‚ which can be further described as passive and active transport‚ five experiments were conducted. These tests were done over simple diffusion‚ facilitated diffusion‚ osmosis‚ filtration‚ and active transport by changing and observing different variables and how they affect transport through the membrane. Obtained was the understanding of the changing of the molecular weight cut off in a membrane‚ and how it does not play a part
