I got this incorrect any ideas

Order the steps that cause a shoot to bend toward a
light source.

Starting with light shines on one side of a shoot and
ending bends towards light source.

Photoreceptors in the shoot sense the location of the
light

The concentration of auxin increases on the shaded side
of the plant.

Cells on the shaded side of the shoot
elongate

Auxin activates proton pumps, decreasing the pH of cells
on the shaded side of the shoot.

Acidification breaks hydrogen bonds in the cell wall and
activates expansins.
