The passage describes some glycolysis reactions. Select the appropriate term for each blank to complete the passage. In the first reaction of glycolysis, glucose is converted to glucose 6‑phosphate . The phosphate comes from . A is an enzyme that transfers the terminal phosphate of A isomerase glucose 6-phosphate to fructose-6-phosphate to a substrate. The product of this reaction is then isomerized reaction, giving Fructose-6-phosphate is then phosphorylated by a second isomerase fructose 1,6-bisphosphate
