Auxin enhances cell elongation in all of these ways except
A)increased uptake of solutes.
B)gene activation.
C)acidification of the cell wall, causing denaturation of growth-inhibiting cell wall proteins.

E)cell wall loosening.

Question

Quizplus · Accepted Answer

Auxin does not cause acidification of the cell wall, which denatures growth-inhibiting proteins. Instead, it causes a decrease in pH, which activates enzymes that loosen the cell wall and promote cell elongation.
