The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

Urinary Analysis Bio 224L Wed. 9:30-10:50 Amie Gohn 11-30-11 Mr. Brown Introduction There are many different factors that can affect urine including volume‚ urine concentration‚ and pH levels. Factors that affect urine volume are fluid intake and reabsorption‚ which affects the amount of urine released. Urine concentration is measured by the concentration of dissolved solids present in a person’s urine‚ which is affected by water intake levels as

55. a) Cuticles on the outermost layer of angiosperms are clear‚ which allows for light to pass through. The leaf is shaped in a way that will allow it to absorb more sunlight and be more efficient. Photosynthesis takes place in the spongy parenchyma and the palisade parenchyma. In order to obtain food‚ it is controlled by the stoma which controls the passage of gas and water. b) Water and food is transported through the xylem. The water will eventually be transported to the leaf tissue while the

MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased

ABSTRACT: Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactase enzyme. The measurement of light absorbance levels of different solutions based on both the concentration of o-nitrophenol (ONP) as well as the pH of the solution tested. To begin with‚ differing concentrations of ONP were tested to find the absorbance levels of ONP. Three different pH values‚ 5‚ 6‚ and 7‚ in solution‚ were tested over a period of 8

Experiment for the measurement of carbon dioxide and oxygen concentrations and their functions during the act of breathing. Introduction: Humans‚ like all living organisms need‚ O2 in order to live‚ they take the necessary O2 from the atmospheric air. The O2 is transferred from the blood to all cells of the body and serves for oxidation of nutrients for example glucose. By oxidize the nutrients released energy‚ which is necessary for the functions of the human body. During oxidation produces

Aim: To investigate the effect of skin sensitivity in response to cold temperature in different parts of the body by timing the maximum amount of time in which ice-pack can be held to that area. Hypothesis: If the layer of skin is relatively thin‚ the nerve response to cold will be the fastest‚ increasing the skin’s sensitivity. This therefore means that the fastest responses to cold will be in the face‚ and specifically the nose. The skin consists of 3 main layers; the epidermis‚ dermis and
