(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 (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
