What body chemical kills bacteria without harming cells?
White blood cells produce hydrogen peroxide to kill bacteria without harming human cells. This process is known as oxidative burst, where the white blood cells create reactive oxygen species to target and destroy invading bacteria.
Why doesn't hydrogen peroxide fizz when i put it in my ear?
The chemical formula for hydrogen peroxide is H2O2. When it decomposes, it separates into water and oxygen gas. The reaction takes this form: 2 H2O2 -------> 2H2O + O2 The release of the oxygen gas is what makes the fizzy bubbles. When you put hydrogen peroxide solution on a wound or in your ears, it saturates the area with oxygen. Bacteria cannot live in this environment, and this is what makes peroxide a good disinfectant. It doesn't really help too much with earwax, though.
Are bacteria cells the same as human skin cells?
No, bacteria cells are prokaryotic cells, meaning they do not have a nucleus or membrane-bound organelles, while human skin cells are eukaryotic cells with a nucleus and organelles. Additionally, bacteria cells are much smaller in size compared to human skin cells.
What do human cells have in common with bacteria cells?
Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.
Why is catalase important for living organisms?
Catalase is an enzyme found in most organisms that are exposed to oxygen. It is important because it catalyzes the breakdown of hydrogen peroxide into oxygen and water. It mainly protects the cell from oxidative damage.
Why doesn't hydrogen peroxide kill human cells?
Hydrogen peroxide can damage human cells by creating oxidative stress, but our cells have enzymes like catalase that help break down hydrogen peroxide into water and oxygen, minimizing its harmful effects. Additionally, human cells have mechanisms to repair the damage caused by hydrogen peroxide.
What body chemical kills bacteria without harming cells?
White blood cells produce hydrogen peroxide to kill bacteria without harming human cells. This process is known as oxidative burst, where the white blood cells create reactive oxygen species to target and destroy invading bacteria.
What is the effect of hydrogen peroxide in the human body?
Hydrogen peroxide is toxic to cells and can cause harm when present in high concentrations in the body. In small amounts, it is naturally produced in our cells and plays a role in immune response. However, excessive exposure to hydrogen peroxide can lead to cellular damage and oxidative stress, contributing to various health issues.
Which is more effective for removing mold: hydrogen peroxide or bleach?
Both hydrogen peroxide and bleach are effective at removing mold, but hydrogen peroxide is generally considered to be safer for both the environment and human health.

What is the similarities and difference between the bacteria and human cells?
Both bacteria and human cells are made up of a cell membrane, cytoplasm, and genetic material, but bacteria lack membrane-bound organelles like the nucleus found in human cells. Bacteria have a simpler structure and are typically smaller in size compared to human cells. Additionally, human cells are eukaryotic, while bacteria are prokaryotic.
What hydrogen peroxide do to scrapes or cuts?
It helps to clean and disinfect an open wound. Works wonders and doesn't sting like isopropyl alcohol would. Do NOT use hydrogen peroxide on human flesh or pets! It kills healthy cells! Not a big issue for minor scraps as it will disinfect, but never use on lacerations or deep wounds.
Are bacteria cells the same as human skin cells?
No, bacteria cells are prokaryotic cells, meaning they do not have a nucleus or membrane-bound organelles, while human skin cells are eukaryotic cells with a nucleus and organelles. Additionally, bacteria cells are much smaller in size compared to human skin cells.
Does the human liver break down more hydrogen peroxide in the summer or winter?
The liver breaks down hydrogen peroxide consistently throughout the year, regardless of the season. The enzyme catalase in the liver helps convert hydrogen peroxide into water and oxygen, a process that occurs continuously to prevent the accumulation of harmful hydrogen peroxide in the body.
Why does hydrogen peroxide bubble on a wound if there is no bacteria?
The reason hydrogen peroxide bubbles when it is put on a cut is because most cells in the body contain catalase. Hydrogen peroxide bubbles when it comes in to contact with catalase. The bubbles are oxygen gas being released.

Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.
