After 14 years of trial and error‚ he developed a process he called Appertizing. Fruits‚ vegetables‚ fish‚ or meat was sealed in stoppered bottles and the filled bottles were immersed in boiling water; the heat sterilized the bottles and food alike. Appert knew nothing of enzymes or bacteria‚ nor did anyone else in his day. He did observe that when food was heated in the sealed bottles‚ the food remained good as long as the seal was not broken. The food remained edible until the bottles were

The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

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.

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

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment involved
