    Research question What is the effect of temperature Amylase activity? Word count-1453 Background research Enzymes are biological catalysts that speed up a chemical reactions. They do this by decreasing the activation energy(the energy needed to start the reaction) of a chemical reaction. The enzyme present in our saliva is called Amylase. Amylase increases the rate of reaction by decreasing the activation energy needed to hydrolyse the starch molecules. These enzymes have a secondary and

    Does Temperature Affect the Rate at Which Cells Move Through the Cell Cycle? Purpose The purpose of this experiment was to determine if temperature has an effect on the rate of the cell cycle. Background Information The cell cycle is a process by which a cell asexually reproduces. There are four significant phases, G1-phase, S-phase, G2-phase, and M-phase. For this experiment, the subdivisions of M-phase are most important. These subdivisions are Prophase, Prometaphase, Metaphase, Anaphase, Telophase

    The effect of the temperature on the reaction time of human hand responding to a sight stimulus Design Research Question: How does the temperature affect the reaction time of human hand in responding to a sight stimulus? Hypothesis: Temperature is an important factor in regulating blood supply and nerve signals. Lower temperatures decrease the nerve signals from brain to hand, thereby slow the reaction (Ascroft). When the hand is submerged in cold water, the sensory receptor nerves in the skin

    Design: 1. The effect of temperature on the rate of reaction of an enzyme (amylase). 2. Research Question: a. How does temperature affect the rate of reaction of amylase? 3. Hypothesis a. As the temperature increases, the rate of reaction of amylase also increases. After it reaches the optimum temperature, the rate of reaction will start to decrease until all the enzymes are denatured. 4. Background a. Amylase is found in the saliva (mouth) of humans. It helps to digest food particles in our mouth

    The above tables summarize the average monthly temperature from 2 stations in North Florida, Central Florida, and South Florida. One station is located inland and one station is located near the coast. The average monthly temperatures will be analyzed and compared by regions and then compared as a whole using conceptual temperature models. To begin, the two stations that were chosen in North Florida are located in Panama City and Blountstown. Panama City is located near the coast, thus coastal

    The graph drawn is “ Rate of reaction against temperature of hydrogen peroxide”. From the graph , we can see that as the temperature increase , the rate of reaction increase as well , until the optimum temperature is reached which is pH 5 which the highest rate of reaction is reached. After this point , the rate of reaction started to decrease. This is because the enzyme begins to denature. It means that as the temperature increases , the activation energy is lower thus the rate of reaction increase

    In conclusion temperature change did affect one of the tubes in two very different ways whilst concentration also played a role in the change of the product and reactant. Le chatelier's principle states that through change in temperature, change in concentration and adding pressure you can create an equilibrium where there can be a forward reaction and a reverse reaction. By continuously adding and taking away heat and changing concentration we have created these reactions. When we took away the

    Discussion: 1. In this graph the temperature that the beaker started of at was at -2 degrees because it had just came out of the freezer for 48 hours. There were times where the graph plateaued out and times when the graph had an incline. There was an incline when the results reached 42 degrees until it reached 90 degrees. The graph plateaued out when the temperature reached 26 degrees and stayed on for one minute (4mins to 5mins). It also stays on 96 degrees for 2 mins (14mins to 16mins). The results

    I think the difference in temperature can cause convection currents, because like the lava lamp the more hot something is the more dense it becomes then it rises to the top, the more cool something gets the less dense it becomes and it sinks to the bottom. So when plate tectonics go through a convergent boundary it slides under the crust it then has a current, which is caused from convection. Which then spreads. Then it heats up, and rises to the top. Once it 's at the top it cools down and becomes

    done was to figure out “Does the amount of calcium chloride affect the temperature of water?” For the procedure, the experiment asked to record the initial temperature of 75 mL of water. The first trial said to add zero scoops of calcium chloride and stir for two minutes to record the temperature. Once the first temperature was recorded, it must be written from the difference between the initial temperature and the new temperature. Next, it asked to add one scoop of calcium chloride and stir for two

    How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball? The independent variable is temperature. Temperature is either something that is

    Grade 9 Enzyme Lab Report Purpose: Which temperature of potato (freezing, room temperature, boiling) when added to hydrogen peroxide, would produce the most enzyme activity? Research Question: How does hydrogen peroxide break down enzymes? When hydrogen peroxide and enzymes meet, they instantly form a reaction. This reaction is the chemical distillation of enzymes. The reaction is enzymes breaking down and turning into bubbles. How does temperature affect enzyme activity? Potatoes have enzymes

    Question: What are the effects of temperature on heart rate and strength of contraction? The effects of temperature can either increase the heart rate or decrease the heart rate. The temperature can also effect the strength of contraction either by making the contraction stronger or weaker. Background: Explain on the cellular level how dropping warm Ringers solution on the frog’s heart would affect the cells of the SA node. Dropping warm Ringers solution on the frog’s heart would increase the heart

    The volume, temperature and pressure exerted by a particular gas are highly dependent on one another. This is explained by several Gas Laws. Boyle’s Law states that when the temperature is kept constant, pressure of gas is inversely proportional to the volume. Relating this principle to molar volume, the higher the pressure, the smaller the volume the gas particles occupies. When the volume of the container enclosing the gas is reduced, there are more gas particles per unit volume. The gas particles

    Temperature regulation is one of many aspects of homeostasis, the ability to maintain an organism’s internal environment at a comfortable temperature. An organism can be a temperature regulator or a temperature conformer. An endotherm is a regulating organism that maintains homeostasis by producing its own heat thus keeping the internal environment stable regardless of the conditions of the external environment. This means that the metabolism of an endotherm is always at a constant, rapid rate. An

    be the effects of varying temperatures of hydrogen peroxide on the speed of the chemical reaction that occurs by the catalase enzyme within hydrogen peroxide? If the temperature of the hydrogen peroxide is increased to 40° or more the catalase enzymes reaction speed (time it will take for the filter paper to float to the hydrogen peroxides surface in the test tube) will drastically decrease and ultimately the enzyme will become less effective. Independent. The temperature of the hydrogen peroxide

    energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1). These factors include the pH and the temperature of the solution (1). Most enzymes have a preferred temperature and pH range (2). The preferred temperature for catalase falls between the ranges of thirty five to fifty degrees Celsius (4). Temperatures that are too high denature the enzyme and halt the enzyme’s activity (2). Catalase denatures starts to denature at fifty five degrees Celsius (2)
