Why Does Hydrogen Peroxide Bubble on a Wound

Have you ever wondered why hydrogen peroxide bubbles on a cut or wound, yet it doesnt bubble on unbroken skin? Heres a look at the chemistry behind what makes hydrogen peroxide fizz—and what it means when it doesnt.​ Why Hydrogen Peroxide Forms Bubbles Hydrogen peroxide bubbles when it comes into contact with an enzyme called catalase. Most cells in the body contain catalase, so when the tissue is damaged, the enzyme is released and becomes available to react with the peroxide. Catalase allows hydrogen peroxide (H2O2) to be broken down into water (H2O) and oxygen (O2). Like other enzymes, catalase is not used up in the reaction but is recycled to catalyze more reactions. Catalase supports up to 200,000 reactions per second. The bubbles you see when you pour hydrogen peroxide on a cut are bubbles of oxygen gas. Blood, cells, and some bacteria (e.g., staphylococcus) contain catalase but its not found on the surface of your skin. Thats why pouring peroxide on unbroken skin wont cause bubbles to form. Do keep in mind that since it is so reactive, hydrogen peroxide has a shelf-life—especially once the container its in has been opened. If you dont see bubbles form when peroxide is applied to an infected wound or bloody cut, theres a chance your peroxide has exceeded its shelf-life and is no longer active. Hydrogen Peroxide as a Disinfectant Since oxidation is a good way to alter or destroy pigment molecules, the earliest use of hydrogen peroxide was as a bleaching agent. However, peroxide has been used as a rinse and disinfectant since the 1920s. Hydrogen peroxide works to disinfect wounds in several ways: First, since its a solution in water, it helps rinse away dirt and damaged cells and loosen dried blood, while the bubbles help lift away debris. Although the oxygen released by peroxide doesnt kill all types of bacteria, some are destroyed. Peroxide also has bacteriostatic properties, meaning it helps prevent bacteria from growing and dividing, and also acts as a sporicide, killing potentially infectious fungal spores. However, hydrogen peroxide isnt an ideal disinfectant because it also kills fibroblasts, which are a type of connective tissue the body uses to help repair wounds. Since it inhibits healing, hydrogen peroxide should not be used for prolonged periods of time. In fact, most doctors and dermatologists advise against using it to disinfect open wounds for this very reason. Make Sure Hydrogen Peroxide Is Still Good Eventually, hydrogen peroxide breaks down into oxygen and water. Once it has, if you use it on a wound, youre basically using plain water. Fortunately, theres a simple test to see whether or not your peroxide is still good. Simply splash a small amount into a sink. Metals (like those near the drain) catalyze the conversion of oxygen and water, so they also form bubbles as youd see on a wound. If bubbles form, the peroxide is effective. If you dont see bubbles, its time to get a new bottle. To ensure hydrogen peroxide lasts as long as possible, keep it in its original dark container (light breaks down peroxide) and store it in a cool location. Test It Yourself Human cells arent the only ones that release catalase when they are compromised. Try pouring hydrogen peroxide on a whole potato. Next, compare that reaction to the one you get when you pour peroxide on a slice of cut potato. You can also test the reactions of other substances, like how alcohol burns on skin or wounds.

Consequences of Postmodernism in the Movie Free Essays

How the movie â€Å"American Psycho† relates to the post modern society of America in the 80†² IIS Postmodernism was first seen in the late nineteenth century, but after the second world war it was applied to people’s everyday life. â€Å"American Psycho† portraits the reality and consequences of postmodernism through the mysterious life of Patrick Bateman as the â€Å"American Psycho†. Patrick Bateman is the main character of the movie, and the whole world is seen through his eyes. We will write a custom essay sample on Consequences of Postmodernism in the Movie or any similar topic only for you Order Now The moral in the movie is that there are no morals, it is one big twisted game fighting for status. Patriot’s life comes focused on this goal through worshipping the surface through capitalistic, consumerist and narcissistic behavior. The â€Å"Business card† scene definitely displays that Patrick Bateman perceives the world as post modernistic. Nothing has meaning to it in Patriot’s mind, as ideologies, goodness and love. What Bateman can relate to are the materialistic aspects for example the business cards where it meaner everything to him to have the best card which is only an illusion of himself. Bateman and the phenomenon, postmodernism are the idea that nothing is real Just an illusion and that everything is a copy of something that’s already been duplicated. This movie has many different ways to look at it. Many have seen this movie and thought whether this is all real or if it’s Just his crazy twisted mind, making it all up. One thing we can agree on is the fact that Patrick Bateman is a mentally disturbed person. Maybe all this violence and blood displayed in this movie, are the feelings of the author towards the post modernistic society that we have and do live in, this is him showing his hatred towards it. This is why it is irrelevant whether it is real or not, t is this feeling the author has towards this twisted society that you must understand and to feel it you must see it in action. When societies redefine, the people also redefine this is the process we see in Batsman’s life. He is always thriving to redefine himself both through his physical body and through his materialistic belongings. This thriving for the idealistic image is the meaning of life for Patrick Bateman, all of his actions and thought are focused on redefining himself compared to the redefining society. Survival becomes a key point in this society. Bateman is trying to survive in his sick society. By surviving it meaner to keep up with all the materialistic ideologies of the perfect being. His survival for this we see when he does his regular morning exercise followed by a skin mask to the battle of business cards. One of postmodernists big aspects is the value given to the materialistic aspects of society, everything has lost its soul even people are described almost as if they were products. People are no longer Judged by their true selves but through what clothes they wear, what perfume they use and how much money they own. An example from he movie is the big importance of which restaurant to eat at. It is not whether the food is good, it is what image it represents to the surrounding people. Patrick Bateman is trying to sell himself all the time. He does this Just like you would advertise a bottle of coca-cola. He wants the surrounding people to associate him with the best restaurant, business card and even the look of his girlfriend. This is exactly how coca-cola tries to sell us this idea of happiness and fairytale world when you open a bottle of coca-cola, this they do through advertisements as we see it with Bateman, who becomes a product. Creating this image of yourself is pure postmodernism. The movie shows this to us in such a clear way though Patrick Bateman description of himself. â€Å"‘ have all the characteristics of a human being: blood, flesh, skin, hair; but not a single, clear, identifiable emotion, except for greed and disgust. † and â€Å"there is an idea of a Patrick Bateman; some kind of abstraction. But there is no real me: only an entity, something illusory. And though I can hide my cold gaze, and you can shake my hand and feel flesh gripping yours and maybe you can even sense our lifestyles are probably comparable†¦ I simply am not there†. To understand this you must understand that the soul is your true being. Through postmodernism the soul dies due to always having to manipulate and create this illusory image of one self, but by doing this the soul is getting buried so deep beneath this image, that it is almost non-existing. The whole point of a post modernistic life is trying to create this perfect picture of yourself, instead of finding your true self by removing all mindsets and ideologies given to you by this manipulative society trying to give you ideologies, norms and rules that bury our soul. This movie is showing postmodernism at its finest. All values, ideologies and norms have vanished and now they are meaningless. In the end the only thing you can really reflect on is one self. Bateman is wandering around a materialistic â€Å"yuppie society†, where people are so concerned and busy with their outer, status and themselves, that they don’t see how gruesome and crazy Bateman really is. All the violence in itself is not that important for the meaning of the movie. What really is trying to be shown in this movie is this outrage towards the post modernistic society and how it can affect you. How to cite Consequences of Postmodernism in the Movie, Papers
