(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.
Atomic number and mass number. The atomic number of an atom is the number of protons it contains. All the atoms of a particular element have the same atomic number (number of protons). The atoms of different elements have different numbers of protons. For example, all oxygen atoms have 8 protons and all sodium atoms have 11 protons. The mass number of an atom is the total number of protons and neutrons it contains.
