such as temperature‚ substrate concentration‚ enzyme concentration and pH. Enzymes are highly specific and only catalyse one specific chemical reaction‚ speeding up the reaction by lowering the activation energy‚ the energy required to start a chemical reaction (2). At high temperatures and with various mechanical forces or chemical treatments‚ proteins can denature causing it to lose its conformational features and hence its ability to function. The enzyme examined in this experiment‚ rennin‚ is derived

effect different temperatures have on the enzyme (Rennin‚ in milk) Introduction: Rennin is usually present in out stomach it helps us digest protein. Enzymes have optimum temperatures‚ since rennin is an enzyme from the human stomach its optimum temperature would be around 37-38 Celsius‚ optimum pH would be 1-3. If the temperature is too low the enzymes will move around slowly. A temperature that is too high or an incorrect pH would denature the enzyme. Materials: 25 rennin labels Beaker

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

Temperature Rising Global Warming is the increase in the average temperature of the Earth’s near-surface air‚ landmasses‚ and oceans its projected prolongation. Many believe that the Earth is currently facing warming in the ozone layer brought on by the rising levels of trapped gases known as the greenhouse effect resulting especially from pollution. Global warming is‚ in Laymen’s terms‚ altering the balance in energy of the earth (Reid 27). “The topic of climatic change has been in question

changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm‚ the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which

insulated as calorimetry relies on the fact that temperature change only occurs within the solution and that no heat escapes to the surroundings. That is why it is important that calorimeters are well insulated. However‚ heat loss cannot be avoided so scientists‚ when conducting experiments‚ need to choose the calorimeter that allows least heat energy to escape‚ therefore‚ retaining as much heat within the solution Research Question: By measuring temperature change of the reaction between hydrochloric
