 * Cofactor: ** It’s a non-protein chemical compound that is needed to “help” an enzyme that catalyzes a particular reaction. They can be considered as the "helper molecules/ions”. Cofactors can be either inorganic like metal ions or organic compounds like [|flavin]  and [|heme] .

After 2 minutes, in the cup without yeast, the color was still a light blue hue, while Cup B with yeast had a greenish hue to it.

Aristotle** (384 BC- 322 BC ) He was a philosopher from Greece. He was a student of Plato and the teacher of Alexander the great. He wrote on many different subjects and his main interests were physics, metaphysics, poetry, theater, logic, rhetoric, music, ethics, plotics, government, zoology and biology.


 * Lazzaro Spallanzani** was born on January 10th 1729 and died on February 12, 799. He was a biologist and a physiologist from Italy who supported the study of the body's functions and animal reproduction. His research of biogenesis paved the way for Louis Pasteur's investigation.


 * Francesco Redi** was born on February 18, 1626 and died March 1, 1697. He was a physician from Italy well-known for the experiment he did in 1668 which refuted spontaneus generation- a theory also called Aristotelian abiogenesis. At that time people thought that maggots formed naturally from rotting meat. In the experiment, Redi took eight jars and divided them into four groups. In the first jar of each group, he put an unknown object, in the sercond, a dead fish, in the last, a raw chunk of veal. He took the first group of eight jars, and covered the tops with fine gauze so that only air could get in. After several days, he saw maggots appear on the objects in the open jars, but not the opened ones.


 * Louis Pasteur** was born on December 27, 1822 and died September 28, 1895. He was a chemist from France and a microbiologist known for his amazing breakthroughs in the causes and prevention of disease. His experiments backed up the theory of disease, which prevented people dyinig from childbed, and he created the first vaccine for rabies. He was also known for inventing the pasteurization.

They are all related because they studied the human body and living things. Some studied the body and some studied the germs to prevent human body to get sick and die just from an ill-ness like in the old times. They all wanted to know and investigate more about our bodies.

**__Questionnaire:__**
 * __1.__** The nature of Hydrogen Peroxide is that it's made H2O2. It's molecular mass is 34.015 g/mol. It has a very light blue hue, it's colorless in solution. It has an aproximate density of 1.44 g/cm3. This compund's melting and boiling point is -0.41 °C and 150.2 °C. It is soluble in water.

<span style="color: #d95eb2; font-family: Verdana,Geneva,sans-serif;">**__2.__** The living things that use this compund are us :) We use this compund for plenty of things. The main use is to clean and disinfect wounds. Other uses are for bleaching hair, whiten bones for exhibition... If you mix it with baking soda and a little bit of soap you can get skunk odor out, also if a dog swallows a harmful substance, you give him a little amount of H2O2 and it makes it vomit.


 * __3.__** The industrial uses of Hydrogen Peroxide are a lot. One is the manufacture of sodium percarbonate and sodium perborate, used as soft bleaches in detergents. It is also used in chemical processes of certain organic peroxides such as dibenzoyl peroxide, used in polymerisations. Besides that, H2O2 is also used in the Oil and Gas exploration industry for the study of fossils. An important use is in big machinery related to food to clean and disinfect them so there's no possibility of fungus.
