Question:

What is meant by inorganic phosphate is it just PO42- ion or H3PO4?

How is the following equation balanced structurally?

$$A D P + P i + H + = A T P + H 2 O$$

Answer:

In biological systems, phosphorus is found as a free phosphate ion in solution and is called inorganic phosphate (denoted $\mathsf{P_i}$ ). Inorganic phosphate at physiological pH primarily consists of a mixture of $\mathsf{HPO_4}^{2-}$ and $\mathsf{H}_2\mathsf{PO}_4^-$ ions.
