The three things that can cause the enzyme to denature is a large change in pH level, High Temperature, and substrate concentration. According to our knowledge, we know that a large change in pH will cause instability in the protein structure thus resulting in denaturation of the enzyme. From the data, we can see that pH 3 (total:6.3) and 10 (total:6.2) were the slowest because pH 3 is probably the highest acid and pH 10 is the highest base. The highest acid or base pH represents a large change which would cause the enzyme to denature. The fastest pH was 6 (total:34.5), and it seems that there wasn’t a large change which resulted in a stable structure.
Introduction: Enzymes are biological catalysts that increase the rate of a reaction without being chemically changed. Enzymes are globular proteins that contain an active site. A specific substrate binds to the active site of the enzyme chemically and structurally (4). Enzymes also increase the rate of a reaction by decreasing the activation energy for that reaction which is the minimum energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1).
Basically , enzyme speeds up the speed of a reaction by cause of at least a million as in comparison to the rate of the same reaction without the enzyme. Enzymes are extremely specific. Typically a particular enzyme catalyzes only a single chemical reaction or a set of closely related chemical reactions .For any catalyst enzymes do not change the equilibrium point of the reaction. The enzyme alters the forward and reverse reaction by specifically the same factor. One reason for the efficiency and specificity of an enzyme is the way the enzyme interacts with reactant molecule also known as the substrate.
The electro pores reseal spontaneously and the cell can recover. The formation of electro pores depends upon the cells that are used and the amplitude and duration of the electric pulse that is applied to them. Electric currents can lead to dramatic heating of the cells that can results in cell death. Heating effects are minimized by using relatively high amplitude, a short duration pulse or by using two very short duration pulses. In terms of mammalian trans genesis, electroporation is an effective method of introducing exogenous DNA into embryonic stem (ES) cells.
Roles of each consist of the nucleus contain genetic material, which controls the actions of the cell, the cytoplasm is where the most chemical process happens and I controlled by enzymes. The Cell membrane controls the flow to and from the cell, the Mitochondria has the most energy released by respiration. In the Ribosomes protein synthesis occurs, and in the extra parts of the plant structure is functions like the cell wall, which strengthens it. The Chloroplasts contains chlorophyll, it absorbs the light for photosynthesis, and finally the permanent vacuole is filled with cell sap that helps keep the cell
Role of Enzymes in Metabolic Pathways Summary Metabolic pathways are a sequences of steps found in biochemical reactions in which the product of one reaction is the substrate for the next reaction . Metabolic pathways most likely happen in specific locations in the cell. The control of any metabolic process depends on control of the enzymes responsible for the reactions occur in the pathways. After food is added to the body, molecules in the digestive system called enzymes break proteins down into fats into fatty acids, amino acids, and carbohydrates into simple sugars (for example, glucose). Enzymes plays an important role in the different metabolic pathways .
An enzyme is a biological catalyst (protein) which speeds up the rate of chemical reactions without changing the chemical reaction at the end. A chemical reaction is when a substance is changed into a different substance. To begin a reaction, you need energy which in this case is called activation energy. A reaction in a chemical reaction is called a substrate when it is being acted upon by an enzyme that speeds up the rate of a reaction. In addition, the region on the enzyme where the substrate binds is the active site.
In all reactions: chemical bonds in the reacting molecules are broken; this takes in energy new chemical bonds form to make the products; this gives out energy When a chemical reaction takes place energy is either taken in or released. This depends on the relative strengths of bonds being broken and bonds being formed. In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger
Enzymes are proteins that catalyze chemical reaction, and they work best at their optimal conditions (optimum pH, temperature etc.) but when the environment is not close to the optimum conditions, the enzymes denature and do not function anymore1. An excellent example would of the effect of temperature on yeast fermentation would be that the bacterial cells if exposed to very high temperature (above the optimal) would no longer function since their enzymes are denatured. The yeast would produce the most Carbon dioxide in the optimal temperature (45 °C ±1/°C) and other temperatures below the optimal temperature would not produce sufficient Carbon dioxide and any temperature above will produce too much that it will lead to the sinking of the bread and death of yeast because its enzymes have been denatured, therefore the reaction will stop. The bread will certainly sink if is not exposed to the right temperature the yeast will not ferment
In an organism 's body, chemical reactions are constantly taking place. These essential reactions can make or break the well-being of the body, yet the brain behind these changes is often times not recognized. This little brain or “macromolecule” is called an enzyme. An enzyme is a type protein that is able to speed up over 5,000 different reaction types an organism (2). Through catalyzation, the process of speeding up chemical reactions, enzymes attach to a substrate/molecule and break it down so that it can be used throughout the organism.
purpose the propose of this experiment was too see if the chemical reaction of a enzyme can be made faster. Hypothesis I think that a warm environment would be best to make an enzyme’s reaction faster. because a protein can move faster in heat.
