My Superhero Elements Project

1. My Superhero Elements Project

2. Potassium • The atomic number for potassium is 19.The element symbol is k. The element atomic mass is 39.0983.

3. Fruits that has potassium Lime and oranges have potassium.

4. Potassium info • Potassium is an essential dietary mineral and electrolyte. The term electrolyte refers to a substance that dissociates into ions (charged particles) in solution, making it capable of conducting electricity. Normal body function depends on tight regulation of potassium concentrations both inside and outside of cells (1).

5. Potassium information • Potassium is the principal positively charged ion (cation) in the fluid inside of cells, while sodium is the principal cation in the fluid outside of cells. Potassium concentrations are about 30 times higher inside than outside cells, while sodium concentrations are more than ten times lower inside than outside cells. The concentration differences between potassium and sodium across cell membranes create an electrochemical gradient known as the membrane potential. A cell's membrane potential is maintained by ion pumps in the cell membrane, especially the sodium, potassium-ATPase pumps. These pumps use ATP (energy) to pump sodium out of the cell in exchange for potassium (diagram). Their activity has been estimated to account for 20%-40% of the resting energy expenditure in a typical adult. The large proportion of energy dedicated to maintaining sodium/potassium concentration gradients emphasizes the importance of this function in sustaining life. Tight control of cell membrane potential is critical for nerve impulse transmission, muscle contraction, and heart function (2, 3).

6. Banana • A banana has potassium in it and it contains protein .Banana length between 3-9 centimeters.

7. My superhero project • My hero is a grape he saved his friend grapeshia from his enemy the peanut. My grape has potassium and a atomic number 19.
