Again, through the activity of the enzymes
involved in combating ROS and due to the dynamics of these
ions [38,39], one can hypothesise that oxygen species are
present in high amounts in such plants, which was corroborated
by the identification of a high number of enzymes such
as CAT, GPX, APX, and GR. Additionally, the hydrogen ions
thus generated are used by the ATPase to generate ATP.
