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.
What else can I help you with?
Why is free oxygen a problem for many organisms?
Free oxygen can be a problem for many organisms because it is highly reactive and can lead to the production of harmful reactive oxygen species (ROS) like superoxide radicals and hydrogen peroxide. These ROS can damage cell membranes, proteins, and DNA, leading to oxidative stress and potential cell death. Organisms have evolved various mechanisms to manage and neutralize these reactive oxygen species.
Does oxygen make you age?
Oxygen itself does not directly cause aging, as it is essential for survival. However, oxidative stress generated by oxygen free radicals can damage cells and contribute to the aging process over time. It's all about achieving a balance between oxygen intake and managing oxidative stress through a healthy lifestyle.
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.
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.
Antigens are chemical agents that fight cell destroying free radicals?
Antigens are actually molecules that trigger an immune response in the body by activating the production of antibodies. Free radicals are unstable molecules that can cause damage to cells and are often neutralized by antioxidants, not antigens.
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.
Which organelle in a cell uses molecular oxygen to convert and detoxify harmful substances such as alcohol and free radicals?
The organelle that uses molecular oxygen to convert and detoxify harmful substances such as alcohol and free radicals is the peroxisome. Within the peroxisome, enzymes like catalase and peroxidase work to break down these toxins into harmless byproducts like water and oxygen.
What converts free radicals to hydrogen peroxide in a cell?
Specifically peroxidase, the enzyme that resides in the peroxisomes.
Do viruses produce free radicals?
Viruses themselves do not produce free radicals, but their infection can lead to the production of free radicals within host cells. When a virus invades a cell, the immune response may generate reactive oxygen species (ROS) as a defense mechanism to combat the infection. Additionally, the metabolic processes of the infected cells can also increase free radical production. Therefore, while viruses do not generate free radicals directly, their presence can stimulate conditions that lead to their formation.
Does BrO3 have any free radicals?
No, BrO3 does not have any free radicals. The BrO3 molecule consists of bromine bonded to three oxygen atoms, and there are no unpaired electrons present to form free radicals.
When a cell membrane is damaged by a free radical which specific component of the cell membrane is damaged?
The unsaturated fatty acids in the phospholipid bilayer are the specific components of the cell membrane that are vulnerable to damage by free radicals. Free radicals can cause lipid peroxidation of these fatty acids, leading to membrane dysfunction and cell damage.
What substance prevent oxygen from combining to form free radicals?
Antioxidants are substances that prevent oxygen from forming free radicals by neutralizing them. They do this by donating an electron to stabilize the free radical and prevent damage to cells. Examples of antioxidants include vitamin C, vitamin E, and beta-carotene.
A organelle that detoxifies free radicals are known as?
The organelle that detoxifies free radicals is the peroxisome. Peroxisomes contain enzymes that break down harmful substances, including free radicals, into harmless byproducts like water and oxygen. This process helps protect cells from oxidative damage.
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 are oxygen derivatives that cause body damage?
Reactive oxygen species (ROS) such as superoxide anion, hydrogen peroxide, and hydroxyl radical are oxygen derivatives that can cause damage to cells and tissues in the body by oxidizing cellular components like lipids, proteins, and DNA. This can lead to inflammation, cell dysfunction, and even cell death.
