activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

Resistance to Change Paper Organizations initiate change efforts for countless reasons. Failure to properly manage these changes can cause an organization to decline or even fail. Most organizations are faced with ongoing changes due to internal and external pressures. These pressures can lead to strategic changes that affect the entire organization or incremental changes that have a direct impact on a specific area. Given the economy today‚ organizations must continually scan their external

The Life Cycle of Resistance to Change What is change? After doing some research I came discovered that there are many different definitions of the word change. Webster’s dictionary says that change means to give a different course‚ position‚ or direction to (Merrriam-Webster‚ 2010). Whenever you add the word change to organizational it takes on a somewhat different meaning. Organizational change is the term used to describe the transformation process that a company goes through in response to

have introduced multiple models that attempt to illustrate exactly how the enzyme and substrate fit together (See figure 1). In the lock and key model‚ the substrate and enzyme fit together perfectly. In the induced fit model‚ however‚ the enzyme changes to fit the substrate‚ which secures the substrate-enzyme complex even further. Induced fit allows the enzyme to position the substrate so that its ability to catalyze is enhanced (Campbell and Reece‚ 2002). Once the enzyme has broken down or built

this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution.

IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site

The Effects of Varying pH on Enzyme Activity A lab was conducted to test different pH balances on an enzyme. Introduction: Enzymes are protein catalysts that speed up a chemical reaction without being consumed in the process. Enzymes are three-dimensional structures that consist of one or more polypeptide chains. The polypeptide chains form an active site (where a substrate will fit into). Enzyme molecules are folded into a very specific shape held together by the different forces of attraction
