Substrate concentration basically means the amount used for the substrate. The substrate in our experiment was 0.1% hydrogen peroxide. The 0.1% is the concentration amount. Just like temperature and pH, substrate concentration can speed the reaction only up to a certain limit. When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster.
For that I will use light resource for which I will be using a bulb. Number of bubbles produced in the water hyacinth is dependent variable because it increases when distance is less and decreases when distance is kept more. Control Variables: Control variables for this experiments are: Time: The light will be given to the plant for the time duration of 1 minute. It can be controlled by using stopwatch. It it is kept for more time it will produce more bubbles.
According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3). Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which
Proteoglycan contents within the extracellular matrix are increased however collagen will only undergo a small amount of change. The released proteoglycans will bind with water causing thickening in response to tensile and compressive overload (Cook and Purdam 2009). Tendon disrepair stage attempts to regain organisation within the extracellular matrix sctructiure through increased activation of cells along with the possibility of neuronal and vascular ingrowth (G.Andersson etal 2007). This presents issues from a clinical perspective as tendons become too difficult to distinguish (Cook and Khan, etal,
What will 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. Dependent.
Increasing substrate and enzyme concentration will increase the rate of the reaction because more substrate molecules will be colliding with enzyme molecules, resulting in products being formed (1). The increase will eventually have no effect on the rate of reaction since the substrate concentration will no longer be the limiting factor. In other words, the enzymes will become saturated and will work at their maximum possible rate
If the temperature, pH and enzyme concentration is kept constant then the rate of reaction will start to decrease as well as the hydrogen peroxide concentration. Aim: To investigate the effects of changing the concentration of the enzyme catalase that it has on the rate of breaking down the Hydrogen Peroxide solution. Dependant and Independent Variables: The Dependent Variables: Amount of time it takes when the bubbles start to rise till when they stop. The Independent Variable: Amount of Hydrogen Peroxide solution. The Controlled/ Fixed Variables are: • The amount of hydrogen peroxide inserted in each test tube.
Then the time of each reaction was recorded when the solution was completed and turned clear. Reaction rate was then calculated using the initial concentration of I2 and time recorded. If reaction rate increases, the reaction is done faster and the reaction time decreases. The first order reaction is a reaction depending only on the concentration of two reactants. Determination of the rate law and activation energy of a chemical reaction requires a number of steps.
There are several factors affecting enzyme activity. These are temperature, pH, enzyme and substrate concentration, enzyme:substrate ratio, and surface area. Increasing the temperature increases the kinetic energy needed to kickstart the reaction. In a liquid substance, this means that there are more random collisions between the molecules. Because increasing the temperature speeds up the rate of reaction, more
The rate increases with temperature up to the optimum temperature. The rate increases because the enzyme and substrate molecules both have more kinetic energy so collide more often and also because more molecules have sufficient energy to overcome the activation energy. Above the optimum temperature there the hydrogen bonds holding the tertiary structure of the enzyme together break, so the active site loses its specific shape and subsequently, the substrate is not complementary to the active site and cannot form an enzyme-substrate complex so the reaction cannot be
To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before
purpose the propose of this experiment was too see if the chemical reaction of a enzyme can be made faster. Hypothesis I think that a warm environment would be best to make an enzyme’s reaction faster. because a protein can move faster in heat.

It discusses how newer technology has been applied to improve the reverse osmosis process, by making it more efficient and cost-effective and increasing its capacity, than conventional reverse osmosis processes. From the economic analysis provided in the article, the new reverse osmosis process will increase the quality of the water (because a set of two membranes, each with ability to remove at least 90% of salts, arranged in series will be used), the amount of water treated and supplied will be increased, and the cost of energy required to push the water through the membranes will be reduced (because the plant’s design requires less pressure). Therefore new technologies can be used to increase the capacity of desalination plants, and reduce energy consumption and other associated
As much was conducted throughout this lab, the projected completion of this lab displays that ultimately, the higher the temperature of the water, the faster the dissolving rate of the Alka-Seltzer is. In other words, the hotter the water temperature the quicker the tablet dissolves within the water in regards to the amount of time it took to dissolve. Furthermore, this experiment helps to explain that, if water is taken at a higher temperature and Alka-Seltzer is placed within the water, the Alka-Seltzer will take less time to dissolve because the higher temperatures cause the tablet to melt at a quicker rate. This compares to when Alka-Seltzer is placed in colder temperatures, where instead it takes more time to dissolve, because the lower
Abstract This experiment showed that temperature, concentration and pH all affect the rate of enzyme reaction differently. Enzymes are very important in organisms and therefore understanding how and why they work the way they do in specific conditions is crucial. The results showed that an increase in temperature would also increase the reaction rate, until a temperature that was too high, where the enzymes began to denature and therefore the rate of reaction was slowed down. As concentration was increased, the reaction rate continued to increase. The higher the concentration, the more rapid increase in reaction rate occurred.
