Question

Which of the following presents the correct sequence of steps involved in the short-distance transport of solutes across plasma membrane?

A. A-D-B-C
B. D-B-A-C
C. B-A-C-D
D. A-B-C-D
A. Proton pumps provide energy for solute transport, specifically
by pumping H+ out of the cell, which in turn, produce an H+
gradient and membrane potential.
B. H+ and other ions diffuse inward through a co-transporter.
C. Ion channels of plant cell membranes allow certain ions to
pass, and this movement of ions into the cell is mainly driven by
the membrane potential.
D. Plant cells use the energy of H+ gradients to cotransport other
solutes by active transport.
