In most cases, the catalase enzyme reacts with the hydrogen peroxide thus converting it into water and oxygen.
To determine the effects of temperature on potato catalase, an experiment was done. To begin with, the potato was grated using a nutmeg grater while making sure that the grated surface frequently is exposed to the calcium carbonate. Thereafter, grinding of the pulp in a mortar, which had some quartz sand for about two minutes, was done. The pulp extract was placed in between an absorbent cotton and cheesecloth to get rid of the water. Thereafter, it was placed in a glass bottle with cold water. This was followed by placing it in a water bath at 200C. Five cubic centimeters of Oakland together with a three percent hydrogen peroxide was added immediately the mixture attained the water bath temperature. Shaking should continue to make sure the effect covers the whole mixture.
In most experiments the catalase enzyme is destroyed at temperatures ranging between 660 C and 780 C. however, in a situation involving a potato catalase enzyme, destruction begins at 500 C. There is a correlation in the VANT HOFF velocity coefficient for hemase (Bunzell & Kenyon, 1933). It reads 1.5 in the potato catalase between 0 and 100 C. temperatures above 200 C already start to destroy the catalase enzyme, which in conjunction with the decomposition of hydrogen peroxide makes it difficult to keep the enzymes alive. This is because of the real and total destruction that happens to the catalase enzyme. Hydrogen impurities do not hinder its destruction even under medium temperatures.
In the experiment, it is very clear that temperature is the independent variable while both the potato and hydrogen peroxide are the dependant variables. They are dependent on temperature of which has to take place in the glass bottle or a test tube in that matter. The amount of hydrogen peroxide,

The author provides an experiment, which has 1 independent variable, 1 dependent variable and 1 control variable. The independent variable is the various concentrations of hydrogen peroxide, while the dependent variable is the rate of reaction in terms of oxygen production. The control variable is the temperature of the room and standard pressure.
is the heaviest while is the lightest. Thus, the two isotopes evaporate variantly and their relative proportions, the isotope ratio expressed as : , in water vapour emanating from a particular stretch of seawater depends upon the temperature of the seawater and the existing isotope ratio in it.
The Irish Potato Famine is one of such tragic episodes in our history. Nevertheless, this infamous famine is a given fact of history of Ireland and Great Britain, so it is no wonder that it has been carefully studied by historians, and that some quite different opinions have emerged as to what degree this famine was initiated by natural causes and to what extent the famine was a disaster waiting to happen.
Temperature of a substance measures the average thermal energy or heat of its atoms and and/or molecules. Planck temperature is considered to be the maximum attainable temperature (Anissimov, 2011).
There are numerous forms of energy including heat energy, gravitational
After a few minutes, when the potato had boiled a bit, I took it out of the pan and started peeling off the skin. This exposed the yellow part of the potato.
Once this was done, I set it down for a few
According to the author of the text, the temperature input significantly affects the mean output of the amylase hydrolysis laboratory experiments because temperature affects the number of enzyme collisions. In addition, trend analysis indicates that as the temperature increases at zero time period, the mean output increases.
The perfect economy offers choices that are price-influenced. Question 1. The monopoly market structure is defined as a business environment where the industry and the sole entity are one and the same. In the 2008 Northwest’s monopoly style potato chip industry, there is no substitute for the lone Wongs potato chip products sold in the potato chip market segment.
