both liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚ surface area‚ chemicals‚ and pH will denature the shape of the enzyme‚ not allowing it to do its function. Testing on peroxidase- an enzyme- will be done on an animal enzyme (chicken liver) and a plant enzyme (potato). For testing Hydrogen Peroxide (H2O2) will be poured over the enzymes. When the enzymes in the potato or liver

Abstract The decomposition of hydrogen peroxide (H2O2) in a whole and diced wedges by with The enzyme catalase was observed. The catalase was able to break down the hydrogen peroxide In the diced banana wedge better than the whole banana because after the banana was diced that Increases the surface area allowing the breakdown to flow. The effects of temperature on enzyme In a liver sample were observed under iced‚ boiling‚ 37 degrees‚ and room temperature Conditions. The enzymes became completely

impactful waves of immigration to the United States occurred as a result of the Irish Potato Famine. The famine occurred due to failure of Ireland’s potato crop in 1945 through 1949 (Mokyr 1). Although the famine lasted four years‚ its effects can still be seen in the United States. The influx of Irish immigrants served as the backbone of the industrializing United States and forever changed the nation. Despite the Irish Potato Famine’s impact on the United States‚ it could have been avoided if other nations

What kind of role does hydrogen peroxide and a liver have in their chemical reaction? In the experiment‚ we saw they had a reaction‚ but completed further tests to determine whether they changed after the reaction. Hydrogen peroxide is chemically changed into water and the liver is broken down in the reaction. In the experiment‚ a fresh piece of chicken liver was put into a test tube filled with 3% hydrogen peroxide. We knew a reaction was taking place because the hydrogen peroxide started to foam

Although a blight affected the potato crops of Ireland during the 1840’s‚ the mass starvation was the result of British governmental policy‚ that forced many Irish to immigrate to America. Their immigration had many positive and negative effects on the American people and the economy. Ireland was a country of poverty and nearly half of the families in rural areas were living in mud houses with no windows or furniture. According to the Constitutional Rights Foundation‚ Ireland was not an industrialized

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence
