Lactose is transported via secondary active transport into bacterial cells.Which of the following would be absent from a diagram illustrating the mechanism of this transport system?

Question

Quizplus · Accepted Answer

Secondary active transport does not directly use ATP. Instead, it uses the energy stored in an existing concentration gradient or electric potential to drive the transport of another molecule against its own concentration gradient. In the case of lactose transport in bacterial cells, a proton gradient is used to transport lactose via symport with a proton. This process is not considered direct ATP hydrolysis.
