Oxygen or an oxidizing agent to receive electrons must be present for oxidation to occur in chemical reactions.
Explanation;
Oxidation entails the loss of electrons from these molecules, causing them to become unstable and highly reactive and leading to their eventual reaction with and damage of cell components such as membranes.
-In redox reaction; The ion or molecule that accepts electrons is called the oxidizing agent; by accepting electrons it causes the oxidation of another species. Conversely, the species that donates electrons is called the reducing agent; when the reaction occurs, it reduces the other species.
The larger mass a star has the shorter its life span will be because since it is so large, the more nuclear energy it has to create to keep it up and running. So the smaller the star the longer its life span and vise versa. Hope this helped!
