Antioxidants, found in fruits, vegetables, and nuts, help neutralize reactive oxygen species and prevent damage to cells. They work by donating electrons to stabilize these harmful molecules and reduce oxidative stress in the body. Consuming a diet rich in antioxidants can help protect cells from oxidative damage and lower the risk of chronic diseases.
What else can I help you with?
Where in the body is Reactive Oxygen species produced?
Reactive oxygen species (ROS) are produced in various parts of the body, including mitochondria, peroxisomes, and immune cells like neutrophils and macrophages.ROS are natural byproducts of cellular metabolism that can be harmful in excess, causing oxidative damage to proteins, lipids, and DNA.
Why do your cells die without oxygen?
Cells require oxygen for the process of cellular respiration, which generates energy in the form of ATP. Without oxygen, cells are unable to produce ATP efficiently, leading to cell death. Oxygen is also essential for maintaining the balance of reactive oxygen species in cells, and their absence can lead to oxidative stress and cell damage.
Is the enzyme cataylse the break down of a subtrate molecules?
Yes, the enzyme catalase catalyzes the breakdown of hydrogen peroxide into water and oxygen molecules. This reaction helps to protect cells from damage caused by reactive oxygen species.
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.
How does oxygen slow bacterial growth?
Oxygen slows bacterial growth by affecting the metabolic pathways within the bacterial cells. Aerobic bacteria require oxygen to produce energy through respiration, and when oxygen is limited, their growth is inhibited. Oxygen can also generate reactive oxygen species that damage cellular components, further inhibiting bacterial growth.

What enzyme break down h2o2 to h2o and o2?
Catalase is the enzyme that breaks down hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2). It helps protect cells from damage caused by reactive oxygen species.
How does a free radical destroy animal tissue?
Free radicals have a free reactive oxygen on its molecule that wants to bind to something so it can be stable. Radicals attach to your cells and 'steal' and break down the lipid membrane that holds your cells together. This causes the cells to lyse (leak) and eventually causes tissue damage. Reactive Oxygen Species (ROS) are molecules in our body that prevent this.
What is photooxidative damage?
Photooxidative damage occurs when light exposure triggers the formation of reactive oxygen species in cells, leading to damage of cellular components such as proteins, lipids, and DNA. This can result in cell dysfunction and contribute to aging, skin damage, and diseases such as cancer. Sun exposure is a common source of photooxidative damage.

What enzyme can convert 40 million molecules of hydrogen peroxide to harmless water and oxygen every second?
The enzyme catalase can convert 40 million molecules of hydrogen peroxide to harmless water and oxygen every second. Catalase is found in the peroxisomes of cells and plays a crucial role in protecting cells from damage caused by reactive oxygen species.
What is the function of superoxide dismutase?
Superoxide dismutase is an enzyme that plays a crucial role in protecting cells from damage caused by reactive oxygen species. It catalyzes the conversion of the superoxide radical into oxygen and hydrogen peroxide, reducing oxidative stress and maintaining cellular health.
Why are peroxide ions dangerous to cells?
Peroxide ions are dangerous to cells because they can generate reactive oxygen species (ROS) that can damage cell structures such as proteins, lipids, and DNA. This oxidative stress can lead to cell membrane disruption, impaired cellular functions, and ultimately cell death.
In what two ways do radon destroy genetic information in lung tissue cells?
Radon can damage genetic information in lung tissue cells through direct ionization, where radiation from radon alters the DNA structure directly. Additionally, radon can also generate reactive oxygen species that can cause further damage to DNA in lung tissue cells.
