Answer:
proteins called expansins
Explanation:
The complete question is :
<em>According to the acid-growth hypothesis, auxin causes increased acidity in cell walls, which then activates ____ that disrupt(s) bonds between cellulose microfibrils, allowing cell expansion.</em>
<em>a. a membrane potential </em>
<em>b. an mRNA </em>
<em>c. AUX1 transporters </em>
<em>d. K+ ions </em>
<em>e. proteins called expansins</em>
<em></em>
- The acid growth hypothesis explains the growth of cells and organs in the plants.
- According to this hypothesis, the plant hormone auxin causes induction of the H+ proton extrusion into the apoplast which leads to the activation of expansin which a pH-sensitive protein.
- Expansin is responsible for wall stretching and relaxation and causes hydrolysis of hydrogen bonds and thus helps in cell expansion.
