Which of the following is an energy-requiring step of glycolysis? Electrons and hydrogen ions are transferred to NADH when a phosphate group is added to PGAL. A phosphate group is transferred from ATP to glucose to produce glucose-6-phosphate. Two phosphate groups are transferred from each intermediate to ADP, forming ATP.
