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 protein

C) The elevation of calcium and ROS levels during the early stages of the stress response activates protein kinases and phosphatases

D) ROS activated Ca2+ channel leads to Ca2+  influx from apoplastic space  to cytosol

Arrange the correct order of  following steps involve in ROS generation;

Choose correct statement about Electrocardiogram Augmented Limb Leads.

a. In this type of limb lead system, two of the limbs are connected through the positive terminal of the electrocardiograph, and the third limb is connected to the negative terminal. 

b. In this type of limb lead system, two of the limbs are connected through the negative terminal of the electrocardiograph, and the third limb is connected to the positive terminal. 

c. When the positive terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.

d. When the negative terminal is on the right arm, the lead is known as the aVR lead; when on the left arm, it is known as the aVL lead; and when on the left leg, it is known as the aVF lead.
