transport of sodium potassium pumps will decrease dramatically due to the lessened concentration of pumps. If the same transport was run without ATP. it would not work‚ hence justifying that it is not simple diffusion‚ and rather was active transport‚ which requires the use of ATP. No‚ because the two substances are the same in each beaker‚ causing no effect on Na+ transport as they are at equilibrium. The rate of ion transport would increase when the number of sodium-potassium pump proteins increase

HYPERTENSION Our paper discusses the importance of nutrition and how it plays a part on our health. Specifically focusing on the disorder‚ hypertension. Hypertension is the medical diagnosis term used for when a person has high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. In this paper‚ we go into depth on how certain types of foods increase our blood pressure and what we can do to minimize it. Lifestyle
