Abstract

The conceptual advances introduced by recent discoveries in the field of active transport have triggered a transition from a "black box" approach to a "mechanistic" approach. At present, treating this subject in the graduate setting requires consideration of equilibrium and kinetic experimentation, protein chemistry, mutational analysis and molecular structure, with the aim of defining the "transport machine."
