What is oxidative stress?

Good job!! It was very helpful.

Very helpful. Thanks for providing a clear explanation of what Oxidative Stress is :)

Thanks for that :D

You've done a really good job here, thank you :)
P.S. I wanna live the healthy one :P

good work

Thank you, simple and helpful.

can this cause muscle excitability

(Transcript) Oxidative stress is a state of the body in which there is an excess of free radicals present. A free radical is a molecule in an unstable state because it's missing an electron. To gain stability it takes an electron from a nearby molecule. This can happen in any part of the cellular structure...Because that second molecule is now unstable it in turn needs to gain its stability by taking electrons from another molecule. Now a domino effect of stealing electrons begins. Without mediation, this process can lead to the destruction of cellular structures, in this case the free membrane. Free radicals are produced naturally throughout the body as by products of cellular metabolic process, therefore our cells come equipped with the molecules to get rid of these free molecules. The problem comes when there is an excess of free radicals and our cells can no longer keep up. This is called oxidative stress load.

Oxidative stress can lead to severe cell damage.

Antioxidants are molecules that are able to donate electrons without themselves becoming unstable. Fruits and vegetables contain antioxidants.

Thank you for making this so clear! I feel much more confident about my paper now.

Smoking produces ROS and RNS FREE RADICALS...free radicals produce cancer,diabetes,strokes,Alzheimer's....etc

Does having this oxidative stress feel like having actual stress

this was great!!!!

Thanks for the video, damn this video was made when I was in 4th-5th grade, now its helping me in college.

Great video
