Question

What are examples of secondary active transport?

Answer 1

Secondary active transport

1. Secondary active transport is a type of active transport across a biological membrane in which a transporter protein couples the uphill movement of another molecule or ion against a concentration/electrochemical gradient with the movement of an ion (typically Na+ or H+) down its electrochemical gradient.
2. The glucose symporter SGLT1 is an example of secondary active transport.
3. The sodium-calcium antiporter is another example.
