Question
Chapter 5.4, Problem 2CC
Summary Introduction
To explain:
Why the sodium-potassium pump would not be considered a co-transporter.
Concept introduction:
Co-transport is a process in which one solute is transported down its concentration gradient coupled with the transport of another solute against its concentration gradient. This process is mediated by transport proteins present in the cell membrane called co-transporter.
