experiment was to find out how temperature affects the enzymes activity. For example‚ in Humans if the temperature is too high‚ the individual’s brain enzymes can denature and cause life threatening problems. The opposite can occur as well‚ if the temperature is too low‚ hypothermia can occur and it can be dangerous (Wilson‚ 1996). In the experiment optimal conditions for fungal and bacterial amylase was measured as well. Discovering information‚ such as the optimal temperature‚ can help demonstrate the

The effect on the pH of Distilled water‚ Potato Solution and Commercial Buffer‚ when Hydrochloric acid (0.1 mol/L) and Sodium Hydroxide (0.1 mol/L) is added Mahima Mandava Mrs. Haist September 23rd‚ 2014 SBI4U1 Background Information: The pH is the measurement of how acidic or how basic a substance can be. The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors

Temperature Rising Global Warming is the increase in the average temperature of the Earth’s near-surface air‚ landmasses‚ and oceans its projected prolongation. Many believe that the Earth is currently facing warming in the ozone layer brought on by the rising levels of trapped gases known as the greenhouse effect resulting especially from pollution. Global warming is‚ in Laymen’s terms‚ altering the balance in energy of the earth (Reid 27). “The topic of climatic change has been in question

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

Trypsin is part of the digestive system and degrades proteins‚ making it an enzyme known as protease. [1] It is one of the three principal digestive proteinases‚ the other two being pepsin and chymotrypsin. [9] Trypsin primarily hydrolyses peptides into smaller building-blocks‚ mainly amino acids (these peptides are the result of

Hypothesis: Temperature of water affects the time taken for salt to dissolve Introduction: In this is will be doing a coursework an experiment in which I will be trying to prove my hypothesis? I will do a set of trial experiment and a main one which I will be trying different temperature‚ which I can prove that this will work and to make sure I get hang of it when I do my real experiment. I will also draw a set of graphs in which I can show which can show if this proves my hypothesis. Important

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

Introduction Enzymes are key players in metabolism. A metabolism is the organic processes in a cell or an organism that are necessary for life. An enzyme affects the rate at which a reaction occurs when the activation energy is lowered. In this reaction the reactant is called the substrate which is that combine with enzymes molecules to form a temporary enzyme substrate complex. During this products are formed and the enzyme molecules released is unchanged. For the substrate complex to form the
