Update on Reactive Oxygen Species in Chloroplasts Production and Scavenging of Reactive Oxygen Species in Chloroplasts and Their Functions
The reaction centers of PSI and PSII in chloroplast thylakoids are the major generation site of reactive oxygen species (ROS). Photoreduction of oxygen to hydrogen peroxide (H2O2) in PSI was discovered over 50 years ago by Mehler (1951). Subsequently, the primary reduced product was identified to be superoxide anion (O2 ), and its disproportionation produces H2O2 and O2 (Asada et al., 1974). On...
متن کاملReactive oxygen species: finding the right balance.
Appropriate regulation of reactive oxygen species (ROS) has a significant impact on health and disease. ROS includes oxygen ions (O2̇) free radicals (superoxide [O, 2] and hydroxyl radicals), and peroxides (hydrogen peroxide [H2O2]) and are the products of normal oxygen consuming metabolic process in the body. ROS are small and highly reactive molecules with important cell signaling roles when m...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

متن کاملOxygen Concentration in Isolated Chloroplasts during Photosynthesis.
The O(2) concentration in intact and osmotically disrupted isolated spinach (Spinacia oleracea, L.) chloroplasts during photosynthesis was estimated. The chloroplasts were allowed to reduce 3-phosphoglycerate, CO(2), or ferricyanide in light until the rate of O(2) production was linear. When the light was turned off O(2) evolution from the chloroplasts continued for a few seconds. This prolonge...
