Well my family has a genetic condition but i wouldnt want to know about my chances of catching it. I would rather remain blind to how long and enjoy how long my life lasts. I wouldnt want to know because then I would feel like I have a time limit. By not knowing I can enjoy every breath i take. Also by not knowing I wont have to worry my kids about me. Like last time I had a cold they called a doctor and scheduled an appointment just for a few sneezes and coughs. Also if I told my kids then they would feel like they have a time limit on their lives to. I am just going to live my life to the best. Plus if anything does happen to me I am only like two minutes away from a hospital.
By sodium and potassium pump.
The sodium-potassium pump is observed in various cellular membranes. They are fueled by ATP, the pump moves potassium and sodium ions in reverse orientation, each against its concentration gradient. In a single cycle, two potassium ions are imported into the cell, and three sodium ions are extruded out.
These pumps are utilized to produce gradients of sodium and potassium ions. These gradients are used to proliferate electrical signals, which travel along the nerves.
