Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction

relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate complex by the lock and key mechanism. It is hypothesized that a greater concentration of product is achieved through

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Abstract The aim of this experiment was to 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.

After we added 2 more mL of hydrogen peroxide‚ the reaction occurred again. Again‚ small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes. 3. After adding more manganese dioxide‚ the reaction occurred again. This time‚ the bubbles being formed were larger; intensity of

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates
