14C-Labeled glyceraldehyde 3-phosphate was added to a yeast extract. After a short time, fructose 1,6-bisphosphate labeled with 14C at C-3 andC-4 was isolated. What was the location of the 14C label in the starting glyceraldehyde 3- phosphate? Where did the second 14C label in fructose 1,6-bisphosphate come from? Explain.
