Question

The image below represents a coupled transport system in a cell
that functions to transport a specific disaccharide into the cell.
a. Four components are labeled in the image (1-4). Identify the
components by name and briefly describe their roles in this
coupled transport system.
b. Which of the following scenarios most likely describes the
solutions inside and outside of the cell ? Be sure to propose a
reason for your answer.
pH (inside) = pH (outside)
%3D
pH (inside) > pH (outside)
pH (inside) < pH (outside)

Expert Solution

Step 1

The simultaneous transport of two substances across a biological membrane is said to be coupled transport. Depending on the direction of the movement of two substances, it can be symport or antiport. For symport type of coupled transport, the movement of two substances is in the same direction whereas, for antiport type of coupled transport, the movement of two substances is in opposite direction.
