The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of

Poorly Structured Team Throughout the article “How a Liver Unit Failed” by Alan Zarembo and Charles Ornstein‚ there are many examples that prove the members of UCI Medical Center transplant floor‚ lacked the characteristics necessary to be a successful high-performance team. The first characteristic of a high-performance team is to have a clear and elevating goals. Goals have to be clear especially because individuals do not want to be a part of anything that is not going to be important to them

Lab report nº4 The aim of this experiment was to observe the change of enzyme reaction with different concentration of solution. For this experiment we used potato enzymes (catalase) and hydrogen peroxide in concentrations of 100%‚ 80%‚ 60%‚ 40%‚ and 20% According to P.George: “When catalase is added to hydrogen peroxide‚ there is an initial rapid evolution of oxygen which lasts for about two minutes‚ depending on the peroxide concentration. After this‚ oxygen is given off at a steady rate which

Part I - Introduction Enzymes are proteins that act as catalysts to regulate metabolism by selectively speeding up chemical reactions in the cell without being consumed during the process. During the catalytic action‚ the enzyme binds to the substrate – the reactant enzyme acts on – and forms an enzyme-substrate complex to convert the substrate into the product. Each type of enzyme combines with its specific substrate‚ which is recognized by the shape. In the enzymatic reaction‚ the initial rate

AIR POLLUTION IN THE PHILIPPINES Guides and Tips Home / Blog / Air Pollution in the Philippines Air pollution is a common and frequent problem nowadays. When you are on your way to work‚ you pass by your neighbors’ backyard where he is currently burning their garbage from yesterday‚ then you come across a smoke-belching public utility vehicle‚ then a guy beside you lighted a cigarette and started suffocating you with second-hand smoke. You cannot always depend on your handkerchief on covering

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or

A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown phosphatase analyzed showed it was an acidic phosphatase. Ph 5 had

The effects of pH on mung beans Gloria Cheng Winsy Cheung Lily Wong Christine Yen January 15‚ 1998 Abstract This experiment explores how different pH environments affect the growth of mung beans. The mung beans were grown in water with various pH levels‚ consisted of pH levels 5‚ 6‚ 7‚ 8‚ and 9. A replicated design was used consisting of 3 runs for each pH level. The following results are listed in order of pH levels allowing most growth to least growth of the mung beans: 7‚ 8‚ 6‚ 5‚ and 9. These
