Reactive oxygen species (ROS) are unstable, or reactive, compounds that result from the partial reduction of oxygen. ROS can cause damage to molecules, including membrane lipids and nucleic acids, and may be associated with some diseases. Which of the following compounds are reactive oxygen species? Choose all that apply.

.OH
OH-

O2-
H2O

H2O2

H-

.OH, O2-, H2O2

Explanation:

Reactive oxygen species (ROS) are chemically reactive and unstable species containing oxygen. ROS are formed when oxygen is partially reduced, thus they are all radicals with very high reactivity, attacking membrane proteins such as ion channels etc

Examples include peroxides (H2O2), superoxide (O2-), hydroxyl radical (.OH)

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
