Transport of protons from the cytoplasm causes their activation with the uptake of potassium ions.
Their function is inhibited by the ABA hormone, and Zeaxanthin is involved in the activation of these structures. Transport of protons from the cytoplasm causes their activation with the uptake of potassium ions. They are inactive during the day in organisms that use malic acid in their metabolism, and they involve the opening and closing of two guard cells to allow for the diffusion of gases, called transpiration. For 10 points, identify these structures, which are involved in the exchange of carbon dioxide and water vapor in plants.
