In our hypothesis we predicted that the enzymes in the pineapple will denature when the temperature is changed. The prediction was partly correct. Pineapples have special enzymes that denature gelatin molecules. Which is the reason why the pineapple and gelatin test tube remained filled with liquid‚ instead of turning into jelly which gelatin does when it’s molecules are not disturbed. Why our hypothesis was partly incorrect was lacked depth in that when changing the temperature by heating the pineapple

the activation energy of a reaction Enzyme is 3D – allows it to associate with substrate (molecule that will go thru reaction) Enzyme brings two substrates together in correct orientation (dehydration synthesis) or stresses bonds of substrate (hydrolysis) - lowers activation energy for new bonds to be formed/ broken Different types of cells have different types of enzymes – affects structure/function of cell Implication: Enzymes are vital for living things in that it speeds up reactions that‚

THE ROLE OF PROTEIN MISFOLDING AND AGGREGATION IN BSE When a protein misfolds it changes its behavior and function. If it becomes hydrophobic after once being polar. The properties and functionality of the protein are no longer useful to the organism and disaster results. PrPSc is hydrophobic‚ it avoids water inside of the cell…it attracts and attaches other proteins to misfolds and become hydrophobic …Misfolding spreads because the PrPSc act as chaperone proteins to convert PrPc TO PrPSc and

Design your own experiment: Effect of pH on enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases

Pharmacokinetics The pKa of Bupivacaine is 8.1. It possesses a great degree of lipid solubility and is highly protein bound. It is 14 times more potent than lignocaine. Absorption and distribution The site of injection‚ dose administered‚ addition of vasoconstrictor agent and volume of drug influences the systemic absorption of local anaesthetic. A local anaesthetic solution distributed to an area of greater vascularity leads to greater rate and degree of absorption. The final plasma concentration

in this important step. Water‚ acting as the Lewis base‚ removes a proton from the carbon bonded to the nitro group‚ an aromatic benzyl structure is created again: nitroacetanilide; thus ending the nitration reaction (1). Next‚ an acid-catalyzed hydrolysis reaction occurs to remove the acyl group. The nitroacetanilide receives a proton from the sulfuric acid and the double bonded oxygen becomes positively charged. A sp3 hybridized carbon compound is formed once the water attacks the carbon bearing

Introduction: Dependence of Methane Production on Ambient Temperature in Bovine Waste The purpose of this experiment was to determine the effect of temperature in bovine waste on the amount of methane evolved. The hypothesis stated that the bovine waste heated to 48.9oC would produce the most methane. The manipulated variable in the experiment was the temperature of bovine waste. The responding variable was the amount of methane evolved from the waste. The experiment can be applied to real world
