Source of energy in the phosphotransferase system of active transport of sugars in bacteria is

Question

Quizplus · Accepted Answer

The phosphotransferase system (PTS) in bacteria involves the transfer of phosphoryl groups from phosphoenolpyruvate (PEP) to incoming sugars, resulting in their uptake and phosphorylation. Therefore, the source of energy in the PTS is PEP. The other choices listed are not involved in the PTS or the source of energy for this system.
