Identify the step, in which phosphorylation occurs with the help of inorganic phosphate and not ATP.

Step-by-step solution

In glycolysis, the conversion of Glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is catalyzed by the enzyme glyceraldehyde-3-phosphate dehydrogenase. During this step, oxidation of Glyceraldehyde-3-phosphate occurs, and inorganic phosphate ( H₃PO₄ or P_i ) is added to form 1,3-bisphosphoglycerate. ATP is not utilized in this phosphorylation step. In the conversion of Glucose to Glucose-6-phosphate, ATP is used as the phosphate donor. In the conversions of 1,3-bisphosphoglycerate to 3-phosphoglycerate and Phos
