Abstract: After reviewing the basics of enzymes and catalysis‚ we take a dive into the wonderful world of catalase. Beginning with establishing a base line of just how much hydrogen peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much actually reacted after 300 seconds of catalyzed reaction. Follow the experiment from the beginning steps right to the end as you see where the students went wrong‚ interpretation of the results‚ and great answers to work sheet

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

Experiences…How do they make you‚ “you”? What do you think makes you‚ “you”? I think your culture‚ religion‚ and experiences contribute to make a person who they are. I believe that certain aspects of humans and their experiences work together to create a person. For me‚ culture or religion can help shape a person’s characteristic because they play important roles in affecting how they view life. Another characteristic that can influence who or what a person is‚ is their experiences. When you experience

Enzymes Enzymes are… * Biological catalysts Lower the energy level needed for a biochemical reaction to occur. This energy level is called activation energy. * Proteins Polypeptide chains made up of 100’s-1000’s of amino acids in a specific sequence. * Do not get “used up” in a reaction The number of “uses” of an enzyme depends on the enzyme. * Work more efficiently at certain optimum temperatures. * They are “reaction-specific”. Each enzyme is included in one reaction.

mistrust the American health care system due to difference in medical remedies and the language spoken. I know first-hand that my mother would prefer to have a Ghanaian physician‚ as opposed to the general white American doctor. Anne Fadiman wrote a successful award-winning book called‚ The Spirit Catches You and You Fall Down‚ which highlights how the cultural differences between the Hmong culture and American medicine jeopardized the health of a little girl named Lia Lee. The story brings into light

8 months before the story the Curtis brothers parents died in a car crash. They could’ve been Socs before it happened or maybe they were Greasers. Why’d they have to join a gang of Greasers? Could they have joined the Socs instead? This is why Pony and his brothers joined the Greasers. They had to join the gang after their parents had died. When their parents were alive‚ why join a gang? They didn’t need to at the time while having nice parents to provide and be a family so they didn’t need a gang

time‚ making the war between worlds reality. Nothing that I was grown to know‚ or to believe‚ was true today. As a nonbeliever‚ I was made to believe that nothing existed outside of Earth. I didn’t believe in God‚ I believed in science‚ in what I could see‚ in the physical because to me there was no spiritual. But as swarms of people soon flooded the streets‚ I soon became something I never thought I would become…a believer. The areas of the cities where we were evacuated to were distinct in smell

You must do things you think you cannot do Honorary guest‚ lecturers‚ parents‚ fellow graduates‚ good afternoon. I am your valedictorian Oshane Thomas and I am charging you today to do the things you think you cannot do. The important actions aren’t easy. They are hard because of our fears. No one is without them. One of my fears is being here today talking to you. On preparation for graduation‚ I was notified that I had to deliver a speech and the thought of actually doing it terrified me

difficult to assess why people break the law. Although this process may be difficult‚ it is not without merit. In this paper I will discuss my personal opinion on crime causation and how my life experiences have shaped these views. I believe this process is important because one must always be aware of their attitudes and biases when critically examining social phenomena. I believe that there are three levels in one’s life that can increase his or her likelihood to break the law. On the macro level

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration
