WebSep 30, 2024 · The tonoplast or the vacuolar membrane helps in the facilitation of moving the protons or H + ions from the cytoplasm to the vacuole against the concentration gradient. Although this increases the acidity of vacuole but simultaneously also ensures that the cell’s pH is maintained. See Figure 11. WebApr 7, 2024 · SUTs transport sucrose to the other layer of the plasma membrane through the energy generated by membrane potential difference formed by H+ -ATPase, which has main functions: transport sucrose from the leaves to the phloem, and ultimately to the reservoir organs, such as tubers, roots, and fruits.
