(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 number of protons in the nucleus is equal to atomic number, Z while the number of neutrons in the nucleus is sometimes called neutron number, N. Mass number gives the approximate atomic mass of the element. For example, mass number of magnesium is 24 as it contains 12 protons and 12 neutrons in its nucleus.
