reaction. Life would not exist without the presence of enzymes (Phillips‚ 2017). Through chemical reactions‚ this energy is created and is controlled by a catalyst‚ enzymes. Enzymes are known as proteins that are produced in living cells that speed up the metabolic processes of an organism. These catalysts speed up these reactions by decreasing the activation energy‚ how much energy is needed for a chemical reaction to happen (WBC‚ 2015). An enzyme-substrate complex forms when a substrate attaches to

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the

Investigating travel and tourism industry There are 8 main components of travel and tourism industry. They are : 1- Accommodation- this is the most important component in the travel and tourism industry. Accommodation may include hotels‚ guest-houses‚ lodging-houses‚ bed and breakfast‚ inns and motels. 2- Transport- a good transportation system is very important for a travel and tourism industry‚ whether people are on business‚ travelling for leisure or visiting friends and

The Behavior of Proteins: Enzymes Enzymes are Effective Biological Catalyst Catalysis- speeds up metabolism to allow production of products. Enzymes- Highly specific and most efficient catalyst that speeds up metabolism or rate of reaction in organisms by factor up to 10^20 (globular proteins) Nonenzymatic catalyst- enhance by 10^2 -10^4 Ribozymes- acts for catalytic activity in RNA’s Kinetics versus Thermodynamics Standard free energy change- difference between the energies of the reactants

substrate concentration‚ the enzyme is working at “maximum efficiency.” With a concentration at 40‚ it produced 2‚339 products. 2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though. 3. When the concentration is at low substrate‚ most of the enzyme molecules are not filled

The Effect of Substrate Concentration on Initial Reaction Rate The purpose of this study is to identify the 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

The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of
