Adding Enzymes to Improve Beef Tenderness By Chris R. Calkins‚ Ph.D. and Gary Sullivan‚ University of Nebraska Importance of Beef Tenderness Beef palatability is affected by many factors and tenderness is cited as one of the most important. Consumers are willing to pay a premium for a guaranteed tender product with the potential to increase the value of the middle meats over $60 per carcass (Miller et al.‚ 2001). Consequently‚ the meat industry is in a continual search for methods to improve the

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

like: "Salivary Amylase is a an enzyme that digests starch into di- and monosaccharides. Since it’s a salivary amylase‚ the enzyme works best at an alkaline pH of 7‚ in other words‚ the optimum pH is 7. At this pH‚ the rate of amylase activity will be at it’s highest. A pH that is much lower (very acidic) or much higher (very alkaline) will denature the enzyme permanently (specifically the active site)‚ and the enzyme can’t function anymore. The activity of the enzyme will decrease as we increase or

required to submit some of these for assessment but these are for SJII purposes only and will not form part of your final Biology grade for the IB. Internal Assessment is formal assessment that you are required to complete on your own and will be marked by your teacher. The grades are submitted to the IB and the work will form approx 24% of you final IB Biology mark. These pieces of work are very important and you will have many opportunities to obtained good results. Internal Assessment

HB105: Introductory Physiology The Action of Enzymes Introduction An enzyme is located in all living cells‚ and is a complex protein molecules. These protein based molecule act as a catalyst. This is a compound that aids chemical reactions without its own structure and state being changed during the process. Catalysts speed up chemical reactions‚ changing substrates into specific produce. Without these enzymes life would not exist. Enzymes are fundamental to all living things as they speed up

Examination of the Effects of Inhibitory and Non-Inhibitory Competition‚ Enzyme-Substrate Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline

The purpose of this review paper is to discuss the effect of temperature on enzyme- catalyzed reactions. This is relevant because many diseases can be diagnosed and controlled by the processes of enzyme activity (Worthington 2015). If more information is not found about enzyme activity and how it is affected‚ many diseases may go undiagnosed and uncontrolled. Temperature is a type measurement that does not only consist of heat. It is the measurement of the mean kinetic energy of any group of particles

Structure: Enzymes are globular proteins that act as catalysts‚ they have a specific 3D shape that is the result of their amino acid sequence. There is a specific region of the enzyme that is functional‚ this is called the active site. The active site is made up of a small number of amino acids and forms a small depression within the larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate

To investigate the effect of temperature on an enzyme controlled reaction Introduction and planning For the investigation of enzymes‚ I am going to conduct an experiment to see how temperature can affect the rate of reaction of enzymes by testing it with starch. The enzyme that we are going to use is called amylase. We are going to test this enzyme with starch. By mixing amylase and starch solutions together under different temperature conditions‚ we can record the rate of reaction by taking a

that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new cells. Enzymes also help
