Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Introduction Fossil Fuels are the most important energy sources in our world today. The overwhelming majority of the huge amount of energy used in the world comes from the burning of three major fossil fuels: coal‚ petroleum‚ and natural gas. Fossil fuels are a non-renewable source of energy‚ and there is no other . They are formed over a very long period of time; the fossil fuels on earth today were formed from plants and animals that lived up to 300 million years ago. These fossil fuels are found in deposits

Biodiesel Fuel The biggest problem the United States faces today when we talk about becoming energy independent is replacing the gas we use to power our vehicles. When we talk about replacing gasoline as the fuel we use to power our vehicles‚ biomass‚ hydrogen‚ and fuel cells are the three most talked about alternatives. Biomass‚ which is organic material made from plants and animals‚ contains stored energy from the sun. Biomass in the form of bio fuels can be used to make the same products

(electron carrier) and 2 ATP (adenosine triphosphate) molecules. The first step of glycolysis is the energy investment phase. In which 2 ATP’s are added to the Glucose molecule‚ which produces 2 ADP’s and Fructose 1‚ 6-biphosphate. This is followed by the energy payoff phase. In this phase NAD+ is reduced to NADH and ADP is reduced to ATP. The total number of ATP created is 4 and 2 NAHDH. After the energy payoff phase what is left is 2 pyruvates. Fermentation then takes place only in the absence of oxygen

Lab Report Microscopic Study: Investigating Osmosis in Red Blood Cells Lab Report Investigating Osmosis in Red Blood Cells Introduction: The flow of water across a permeable membrane is called osmosis‚ and during this process‚ water moves down its concentration gradient. A solution surrounding a cell is hypertonic if it contains more solute particles than the inside of the cell‚ and the water will move out of the cell into the surrounding hypertonic solution by osmosis. If the solution

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

supervisor Ms. Ehnar Jiy conducted. In this lab‚ i wanted to know if more active cells in our bodies require more energy. I started of by taking five samples of three different types of cell (skin cell‚ muscle cell and lung cell) and counted the mitochondria present in each by viewing the cells under a powerful optical microscope. According to my data‚ i found out that my hypothesis was accurate‚ i predicted that more active cells in our bodies require more energy then there will be a noticeable increase
