Investigating the Enzymatic Activity of Catecholase through Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration University of Alabama at Birmingham Burgess‚ B.N. Introduction: Background Enzymes are macromolecules that act as catalysts in living organisms by speeding up chemical reactions without being changed or destroyed by the reaction (Campbell and Reece‚ 2008). Enzymes are able to speed up the rate of a chemical reaction by decreasing the activation energy during the reaction

Discussion The main findings of the present study were that the number of push up significantly in male than female‚ in contrast to the pulse rate‚ could be attributed at least partially to the greater aerobic fitness in male compared to the female students (see Figure 2). With thorough analysis of the results‚ the null hypothesis has been proven correct as there is no significant difference in the mean maximal pulse rate change of subjects who could do fewer than 20 push-ups and subjects

Field investigation of an ecosystem Located 20km out of Portland; Bridgewater Bay has many secluded rock pool locations that are accessible to biologists for investigation. In this experiment‚ the aim was to study small sections of a rock poll that contained a distribution of organisms. These organisms that were located were found in the littoral zone of Bridgewater’s rocky seashore. A littoral zone is made up of a community of aquatic organisms habiting the narrow strip of coast. The organisms

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

Effects of Temperature on Enzyme Biology Introduction In order to understand the activity of enzymes at different temperatures the ability of the enzyme to function can be measured. This is important in many applications such as Polymerase Chain Reaction for forensics as well as genetics research where manipulation of temperature-dependent enzymes allows for replication of DNA segments. Bennett states‚ “when the energy - measured

the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of 4oC‚ Room

Abstract By working with physical isopods‚ ordinarily known as pill bugs‚ sow bugs or roly- polies‚ we tried whether these sowbugs favored a dark spot to a light place. Included in the lab are a few outlines and tables sketching out our aftereffects of the test. We measured recurrence

amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid at the active site. PH changes affect the structure of an enzyme molecule and therefore affect its ability
