(Na + -K +)-ATPase (2) o ATP transiently phosphorylates Asp to form a high energy intermediate = All P-type ATPases o While every single reaction step is reversible, the entire transport cycle is not.
Atomic mass of magnesium (Mg) is 24.305 g/mole The atomic number is 12.
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equâ¦ivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
