Free radicals contain a non-paired electron (they have 1 less electron than they should have), making them super-reactive. These radicals can cause mutation by reacting with the nitrogenous bases on our cell's DNA. Some mutation are harmless, very few are beneficial but most of them are dangerous because they mess up with the protein production in our cells. Remember that proteins are pretty much the basis of life.

∙ 15y agoFree radicals are seen to damage:
- Cellular organelles
- DNA
- Proteins
Any damage caused to these components is reflected in the general health of the cell. In addition, free radicals impose oxidative stress on cells and promote the aging process.

∙ 8y agoAt the right time and place they can cause rare chemical reactions to occur ...
but their "side effect" is that they cause considerable cell damage.
A good third of cell metabolism is spent getting rid of free radicals and the damage they cause.

∙ 10y agoCell damage by free radicals is called oxidative stress, also oxygen radicals can alter the DNA thus causing the cell to malfunction.

Why don't chlorine molecules decompose to give Cl free radicals please explain in terms of kc?
Chlorine molecules will break down when exposed to UV light and create CL free radicals. CL molecules will freely colide with other molecules and create free radicals. I cannot find a specific reason for why CL doesn't decompose.
Can too much oxygen make you dizzy?
It is possible that an engine can run with insufficient fuel or too much oxygen. Under those conditions the valves and /or pistons can be seriously damaged. In the past, when using carburetors, the problem was solved by using more fuel. Today's engines use EGR valves to prevent engine damage when the computer cuts back on the amount of fuel used.
What is oxidation of cells?
Oxidation is the revolution of electrons. Oxygen electrons that are allowed to move freely create a condition of free radicals. These free radicals react in such a way that they have a physical effect on electrons of the objects they come in contact with. Causing a shift or movement of loose electronsIn some materials it creates an accumulation in others decay.Free radicals in cells causes cell decay.Millentum 12, November 2009A cell oxidation occurs inside in a Hem protein made up of four different polypeptide globin chains that contain between 141 and 146 amino acids called Hemoglobin, inside of this hem protein there is a hem that contains an Iron ion responsible for many functions and one of them will be the transportation of diatomic gases. In another words it carries Oxygen atoms within to where it is required in a life form. In order to properly transfer oxygen thru the body, Iron Ions need to oxidize at level 2 which means carry only two atoms of oxygen. If the Iron Ion oxidize let's say to a higher level it will not let go the oxygen atoms; therefore, it doesn't transport oxygen like it suppose to, there is no oxidation. Research must be done very carefully and thoroughly, since it involves many micro organisms and many functions. This is just a quick answer to the question. And all thought I am not a doctor or a biologist, I study many form of science which I have confronted the same question during my investigations before.
Where does the free oxygen in Earths atmosphere come from?
The free oxygen bubbled up from the oceans.
The primitive earth's atmosphere did not contain water vapor free nitrogen free hydrogen free oxygen inert gases?
free oxygen
Which organelle in a cell uses molecular oxygen to convert and detoxify harmful substances such as alcohol and free radicals?
peroxisomes
What are oxygen derivatives that cause body damage?
Free Radicals
What cell organelle possesses oxidise enzymes that function in neutralizing harmful free radicals?
The cell organelles that possess oxidase enzymes that function in neutralizing harmful free radicals are the peroxisomes. They are also known as microbodies and can be found in almost all eukaryotic cells.
Will large numbers of radicals within the body increase the risk of coronary heart disease?
Oxygen free radicals will :D
Antigens are chemical agents that fight cell destroying free radicals?
true
How do anti oxidants relate to free radicals?
Antioxidants are needed for the prevention of cell deterioration. When cells deteriorate it can lead to viruses, cancer and other diseases to form. Free Radicals are atoms that are slightly distorted. Cells can have damage from free radicals and antioxidants help repair the damage.
What has the author Pieter Biemond written?
Pieter Biemond has written: 'Oxygen free radicals in rheumatoid arthritis'
What converts free radicals to hydrogen peroxide in a cell?
Specifically peroxidase, the enzyme that resides in the peroxisomes.
Is chocolate good for the heart?
Dark chocolate has anti-oxidants which are chemical compounds that can bind to free oxygen radicals preventing these radicals from damaging healthy cells throughout the body.
Why is it important for the cell membrane to be selectively premeable?
It makes it harder for viruses and free radicals to reach the nucleus.
Why is super-oxide dangerous to the body?
superoxide is damaging to body as it is quixkly metabolised to free oxygen radicals. these radicals damage cells, cause atherosclerosis, cancer, and other metabolic conditions.
When was Free Radicals - film - created?
Free Radicals - film - was created in 1979.
