Patrick McCrystal Enzymes: Natural Catalysts Enzymes are catalytic proteins‚ meaning they speed up chemical reactions without beingused up or altered permanently in the process. Although various enzymes use different methods‚all accomplish catalysis by lowering the activation energy for the reaction‚ thus allowing it tooccur more easily. Enzymes have very specific shapes (conformations). Part of the conformationis the active site of the enzyme‚ where the actual catalysis occurs. The specific molecule

Measuring poverty Poverty is the condition of lacking basic human needs such as food‚ clean water‚ health care‚ clothing‚ and shelter due to the inability to afford them. This is also referred to as absolute poverty or destitution. Relative poverty is the condition of having fewer resources or less income than others within a society or country‚ or compared to worldwide averages. When measured‚ poverty may be absolute or relative poverty. Absolute poverty refers to a set standard which is consistent

Digestion and Enzymes – APP. Hypothesis: The enzyme‚ Amylase which is used to break down carbohydrates will work the best when heated at 40°C. Also‚ as the temperature increases the reaction rate of amylase increases too. However‚ the reaction rate of amylase will start decreasing when the temperature reaches the enzyme’s optimal temperature. Many enzymes are specific for a certain substrate. For example‚ lipase is a specific enzyme for fat substrates and protease‚ a specific enzyme for protein

Analysis of Oxygen Bearing Organic Compounds James Matthew Jocson*‚ Gianvittorio Lanta‚ Chiqui Ann Llamado‚ Jeron Manaig College of Science Department of Biology University of Santo Tomas‚ Manila‚ Philippines Abstract Five oxygen-bearing organic compounds were given namely Methanol‚ 2-propanol‚ tert - butanol‚ formalin‚ and acetone. Different tests were done to each sample to differentiate their characteristics. These test were Dichromate test‚ Tollens Test‚ DNPH test‚ Iodoform Test‚ and Lucas

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

There are many reasons why enzymes have such a high specificity. The first variable is an enzyme’s primary structure. A primary structure is just a combination of amino acids. There are twenty different amino acids that the primary structure can be created from. Every enzyme has a different order that the acids are placed in and each one has a different number or amino acids. The slightest change in this structure can affect a protein’s conformation and function. The secondary structure is a regular

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria
