Final answer:
The bacterial phosphotransferase system is an example of the use of multiple transporters for one physiological task. It involves the use of different carrier proteins to transport and modify sugars, ensuring their utilization during sugar metabolism.
Step-by-step explanation:
An example of the use of multiple transporters for one physiological task is the bacterial phosphotransferase system. This system is a series of carriers that phosphorylates glucose or other sugars upon entry into bacterial cells. It involves the use of different carrier proteins to transport and modify the sugars, ensuring that they can be used during sugar metabolism. The phosphotransferase system is considered an energy neutral system because the phosphorylation of sugars is required during the early stages of sugar metabolism.
