The photosynthetic electron transfer chain (PETC) can produce O2• and H2O2 by reducing O2 using reduced forms of electron carriers. In chloroplasts, the interaction of O2 with PETC is thought to be the major source of ROS, and light is necessary for this ROS formation.
Regarding the reactive oxygen species quizlet, which statement is accurate?
Which of the following is accurate with regards to reactive oxygen species. When O2 is overexposed to electrons, reactive oxygen species are created.
Are ROS produced during photosynthesis?
Innumerable reactive oxygen species (ROS) are generated by photosynthesis. In redox signal transduction, which is crucial for chloroplast to nucleus communication, ROS and antioxidants perform a role. Some chloroplasts have unique signaling capabilities that control both genetic and epigenetic programming.
