Purpose: The purpose of this lab was to test how objects slightly acidic or slightly basic will affect the way catalase‚ the enzyme tested‚ denatures‚ or breaks down. Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials:

BUSI2033 Self Reflection Exercise #3: Myers-Briggs Type Indicator When we think of leaders‚ the first thing that usually comes to mind is an individual who holds significant power such as celebrity‚ high profile athlete‚ CEO of a fortune 500 company or a high profile political figure . Everyone has the ability to become a leader‚ as leaders‚ everyone has the power to not only influence others‚ but inspire and motivate them as well.

chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency is measured through the spectrophotometer which

Finding the Optimal pH of the Enzyme Peroxidase with the Aid of a Spectrophotometer ABSTRACT The peroxidase enzyme was partially purified‚ and the enzyme activity was calculated with the use of a spectrophotometer‚ demonstrating the effect of pH on peroxidase activity. The objective of this exercise was to determine the ideal pH for peroxidase activity. The data concluded that the optimum pH for peroxidase activity is 5‚ and the “standardized” enzyme volume is 2.8mL

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Amylopectin The absorbance value(x) read from cuvette containing starch and water represents the total amount of starch-iodine complex. The absorbance value(y) read from cuvette containing starch‚ water and α-amylase at the respective temperature or pH represents the amount of starch-iodine complex which is left after the enzyme has hydrolyzed the starch.In order to get the amount of product;P (maltose and glucose) formed‚ need to subtract the (y) value from the (x) value.

I acknowledge I am an INFP type having preferences for Introversion‚ Intuition‚ Feeling and Perceiving based on the Myers-Briggs Type Indicator (MBTI) leadership tool. My priorities describe who I am as a leader. I am reserved as a person and as a leader I am known for dedication‚ sympathizing with others‚ finding it easy to relate with issues of group members even when I disagree. As a group leader‚ I have a systematic way of achieving tasks. Before I take a decision for the group‚ I consider so
