The electrons lost from chlorophyll photooxidation are replaced by the oxidation of water. how many electrons are generated from

White raven [17]

There are 2 electrons generated from the oxidation of one water molecule.

<h3>Describe photooxidation.</h3>

The process of a substance interacting with oxygen or losing electrons from chemical species under the influence of light is known as photooxidation. Photooxidation happens in plants when there is environmental stress. It is called photooxidative stress as a result. Reactive oxygen species are produced by the absorption of excess excitation energy in plant tissues. Chloroplasts are harmed by the accumulation of these reactive oxygen species, which is a damaging process in plants. High-intensity light and little $CO_{2}$ are the two conditions that cause this photooxidative stress to occur most frequently. It is a procedure that requires light. Photorespiration in $C_{3}$ plants guards against photooxidation.
