OF INVERTASE FROM YEAST AND EFFECT OF pH ON ENZYMATIC ACTIVITY Jenelle C. Faustino‚ John Gambit B. Garcia‚ Fatima S. Jusay‚ Oliver Alexander B. Lao and Eunice L. Licudine Group 4 2 E Medical Technology Biochemistry Laboratory ABSTRACT Enzymes are substances that are produced by living organisms and act as catalysts in order to speed up or chance a chemical reaction without changing itself at the end of the reaction. Invertase was extracted first from baker’s yeast. Determination of

Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible

Heat and Temperature Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same‚ but they are not.” Heat and Temperature‚ para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place

AUTOMATIC TEMPERATURE CONTROLLED FAN H ere is a circuit through which the speed of a fan can be linearly controlled automatically‚ depending on the room temperature. The circuit is highly efficient as it uses thyristors for power control. Alternatively‚ the same circuit can be used for automatic temperature controlled AC power control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at

huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

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
