The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

The Effect of Temperature on Blow-fly Larvae INTRODUCTION Calliphoridae- comonly known as a blowfly‚ are living organisms which usually are the first insects to colonise a body after death. The blowfly larvae are very useful in forensic entomology. The oldest larvae give an approximate time of death of body. Family: Calliphoridae Order: Diptera Name: Calliphora vicina Aim: To check the influence of temperature of environment on living functions and activity of Blow-fly larvae.

Enzymes lower the amount of energy needed in a chemical reaction. This happens because enzymes are catalysts‚ so they speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has

experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about 98.6oF (Chiras 3). In this

Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

The activity of bees and their lives are strongly influenced by the changing seasons. Each month brings about new changes in behavior to a beehive and its occupants. Obviously‚ a beehive is less active during the colder months and more active when the weather is warm‚ but that doesn’t mean you get to ignore the hive completely while they are inactive. That raises the question: is it better to start a beehive in cold weather or warm weather? Understanding how and when bee activity is altered due to

ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single
