ROS using respiratory burst oxidase homolog (RBOH) or NADPH oxidase for Self- generation mechanism by some other processes , which are involved in ROS generation such as,A) The amino-terminal cytoplasmic domain of RBOH proteins contains four serines (Ser) that can be phosphorylated by CDPKs and two EF hands that can bind calcium directly B) As ROS generation such as H2O2, by putting electron for oxidising oxygen into the free radicals, these electron generation by oxidising NADPH and FADH2 in the cytosolic carboxy terminal of RBOH proteinC) The elevation of calcium and ROS levels during the early stages of the stress response activates protein kinases and phosphatasesD) ROS activated Ca2+ channel leads to Ca2+ influx from apoplastic space to cytosolArrange the correct order of following steps involve in ROS generation; -triyambak.org
