What are strengths and weaknesses of oxygen? will be giving brainliest if you are right :)

Explanation:

Oxygen is a strong oxidizing agent and has the second-highest electronegativity of all reactive elements, second only to fluorine.

Oxygen can damage us though. It can react with many different types of molecules. It can damage things like amino acids, proteins, and the nucleic acids

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
