Stimulates proteins in plasma membranes by pumping H+ ions into the cell wall, lowering pH. 2. Low pH activates enzymes that separate cross-linking molecules from cellulose microfibrils in the wall. 3. Cross-linking molecules are more exposed to enzymes that loosen the cell wall. 4. Cell swells w/ water and elongates because its weakened ...
