Chemistry You live with millions of bacteria in your body. The microorganisms are unicellular prokaryotes, found ma alone or in colonies. Are abundant in air, soil and water, and mostly harmless to humans. Living inside and outside the body, hot and humid environments, where it is easier to find food: teeth, throat and digestive tract. Some are aerobic, which means they need oxygen to thrive and multiply, standing, usually on the skin or respiratory system. The anaerobic bacteria live where there is no oxygen, or in the deep layers of the wounds I or acids. Most bacteria of the body are beneficial and necessary to sustain life, such as lactobacilli, which inhabit our gut. They regulate the functions of that body and protect it from the action of harmful bacteria, while they can feed. Thus, the two sides (and gut bacteria) gain. The biologists call this relationship of symbiosis. But there are bacteria that are harmful the body, causing illness and disease. The bacteria which cause disease are called pathogenic. Cavities in teeth are caused by bacteria, and when you cut yourself, the bacteria that are in your skin can cause infection. Therefore, it is natural to find bacteria, viruses and fungi (microorganisms) in your body. The number of microorganisms in the body depends on several factors, such as immune defense, type of diet, hygiene, food, etc.. Certain changes weaken the body, as some immunosuppressants (act directly on the immune system), smoking and stress can trigger an imbalance that causes the growth of aggressive species of microorganisms, resulting in the development of diseases. Remember that the principle of Le Chatelier is applied when changes in balance. ACTIVITY You understood the principle of Le Chatelier? Consider the information: the soda bottle is a closed system in chemical equilibrium dynamic; carbonic acid is an acidulant (accentuates the acid taste); there is a high concentration of ions H The in the stomach;

Kemija Živite s milijunima bakterija u vašem tijelu. Mikroorganizmi su jednostaničnih prokariota, ma naći pojedinačno ili u kolonijama. Jesu li u izobilju u zrak, tlo i vodu, i uglavnom bezopasan za ljude. Živjeti unutar i izvan tijela, topla i vlažna staništa, gdje je lakše pronaći hranu: zubi, grla i probavnog trakta. Neki su aerobne, što znači da oni trebaju kisik napredovati i množite, stoji, najčešće na koži ili dišni sustav. Anaerobne bakterije žive tamo gdje nema kisika, ili u dubokim naslagama ranama ja ili kiselina. Većina bakterija u tijelu su korisne i potrebne za održavanje života, kao što su laktobacili, koji nastavaju naš trbuh. Oni reguliraju funkcije toga tijela te ga štiti od djelovanja štetnih bakterija, dok oni mogu hraniti. Dakle, dvije strane (i crijevna bakterija) dobije. U biolozi nazivaju taj odnos simbioze. No, postoje bakterije koje su štetne tijela, što uzrokuje bolesti i bolesti. Bakterije koje uzrokuju bolest se zove patogeni. Karijes na zubima koje su uzrokovane bakterijama, a kad se smanjiti, bakterije koje se nalaze u vašoj koži mogu izazvati infekciju. Dakle, to je prirodno naći bakterije, viruse i gljivice (mikroorganizmi) u vašem tijelu. Broj mikroorganizama u tijelu ovisi o nekoliko čimbenika, kao što su imunološki obranu, vrsta prehrane, higijene, hrane, itd.. Određene promjene oslabiti tijelo, kao što neki imunosupresivi (izravno djelovati na imunološki sustav), pušenje i stres mogu izazvati neravnotežu koja uzrokuje rast agresivnih vrsta mikroorganizama, što je rezultiralo u razvoju bolesti. Sjeti se da je princip se primjenjuje Le Chatelierov kada promjene u ravnoteži. AKTIVNOST Vi shvatio princip Le Chatelierov? Razmotriti informacije: soda boca je zatvoreni sustav u kemijskoj ravnoteži dinamičan, ugljična kiselina je acidulant (naglašava okus kiseline); postoji visoka koncentracija iona H u želucu;
