Final answer:
The Phosphotransferase System (PTS) is a specific transport system in bacteria that regulates the uptake and phosphorylation of sugars. It is an energy neutral system.
Step-by-step explanation:
The Phosphotransferase System (PTS) is a specific transport system in bacteria. It regulates the uptake and phosphorylation of glucose and other sugars in the early stages of sugar metabolism. The PTS is considered to be an energy neutral system because the phosphorylation of sugars provides the necessary energy for their transport.
