Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

magnet affect by warm or cold temperatures? This experiment showed that if a magnet is cold‚ then it will have more magnetic pull than a warm magnet. The independent variable is the temperature of magnets. The dependent variable is the magnetic pull of magnets. The experimental group is magnets exposed to different temperatures. The control group is the room temperature magnet. The control variables are the amount of time the magnets are exposed to different temperatures‚ the type of magnet‚ and the

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

Does Adding Salt to Water Make it Boil at a Higher Temperature? Project Design Plan Everyone knows that water boils at 212°F‚ but does adding salt to a pot of water make it boil at a higher temperature? Being a person that cooks frequently at home‚ I wanted to test the debated idea that adding salt to my water will make it boil faster. One of my friends says it does raise the temperature and therefore cooks it faster. My other friend says it only helps it taste better. Literature

JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit juices will then be recorded to see if an increase in temperature will affect the amount of concentration

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

decreased‚ particles are closer together‚ so they don’t move as much because they are low in energy as well as space. Temperature: The question being asked to answer is if temperature is affected by thermal energy. My answer to that question is its affected because when you add thermal energy the temperature increases and it becomes warmer‚ but when thermal energy is decreased the temperature becomes frigid. State of Pure Substance: Is the state of pure substance is affected by thermal energy? My answer

structures and temperature as having knowledge of it leads to a perfection in the structures formation. This is especially so as the structural parameters of FePO4 falls very closely to the values that are limited i.e. too high a pressure causing instability in the thermal conditions‚ thus it is in even greater importance that the amount of temperature used is studied in detail since it is a determinant of thermal stability of the parameters of the present structure.

results that have been gathered‚ it tells a variety of different things. Each temperature attempt was done three times to be accurate. First of all‚ the hypothesis (the higher the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1
