The human body consists of enzymes which allow foods to be broken down and enable organisms to build chemical substances such as other proteins, carbohydrates and fats that are necessary for life. This experiment will be testing the enzymatic reactions with toothpicks. This experiment depicts the process when a substrate binds with an enzyme. However, only a specific substrate can attach to a specific enzyme. This allows the substrate to attach to the enzyme and then disconnect the enzyme overall causing the substrate to break in two. This experiment will also show how molecules that work with the enzymes, otherwise known as substrates, speed up the chemical reaction. Enzymes are known to speed up a chemical reaction because they are catalysts,

There were five different types of enzymes that were used to break down the toothpicks. There was the control, the normal enzyme, the enzyme working in decreased temperature, the enzyme with a competitive inhibitor, and the denatured enzyme. The decrease in temperature was simulated by putting your hands in water for a minute before breaking the toothpicks. The competitive inhibitor was simulated by having two different types of toothpicks and only being able to break one. The denatured enzyme was simulated by having to rubber bands around your fingers.

Having been put in a group according to a Belbin questionnaire, concurring to a score, a role is given, which was applied during the experiment. In this group activity, I worked with other students to investigate the effect of temperature on turnip peroxide enzyme. Taking a look at the experiment as a group a decision was made on who does what, so that we are prepared to start the experiment as soon as we settle into the lab. We worked as a team to plan and carry out an investigation, having coming up with instructions as a step to step of how to do the experiment. Carrying out an experiment with a group to investigate enzyme peroxide from turnips, this enzyme helps with the division of hydrogen peroxide developed in the cells during aerobic
If the substrate fits perfectly into the active site, then the reaction will take place, and those substrates that fit into the active site will also be known as reactants (Clark, 2007). The enzymes increase the rate of reaction, while they also lower the
The way we design the lab was very adequate for us to find the information that we needed. The lab was very simple and to the point. Our hypothesis was that the amount of enzyme affect how fast or slow the substrate is broken down. And by the data we have collected in both trials we know that the amount of enzymes does affect how fast is substrate is broken down. This also means that the less enzymes.
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.
2.1. Isolation of fibrinolytic enzyme from Paenibacillus sp. IND8 The optimized conditions of fibrinolytic enzyme production by Paenibacillus sp. IND8 were described previously [28]. This organism was cultured under solid-state fermentation for 72 h using wheat bran as the substrate.
Enzymes are catalysts, which means they speed up chemical reaction. This chemical reaction produces oxygen gas. In hot substances, the enzyme reaction speeds up. In cold substances, the reaction takes a long time, or will never create a chemical reaction Does boiling a potato eliminate its enzymes? Boiling a potato will speed up its enzyme chemical reaction, but if you heat it up to much it will cook and the reaction will stop because all of the enzymes will be cooked.
Enzymes are proteins that act as biological catalysts, where they are organic compounds and speed up reactions. Enzymes increase the rate of reaction without taking part. Enzymes are specific, where they act on only one substrate as most of them only catalyse one reaction. When an enzyme attaches to the substrate at its active site, it creates an enzyme-substrate complex. Enzymes are folded into a 3D shape which creates active sites where the enzyme works.
The oxidative decarboxylation of Pyruvate is carried out by the pyruvate dehydrogenase complex. This multi-protein complex is composed of three enzymes; 1) pyruvate dehydrogenase, 2) dihdrolipoyl transacetylase, and 3) dihyrolipoyl dehydrogenase. The intermediate products formed by this complex are not released and remain bound to the enzyme. The breakdown of fatty acids by the β-oxidation pathway is carried out by four separate enzymes found in the mitochondrial matrix; 1) fatty acyl-CoA dehydrogenase, 2) enoyl hydratase, 3) β-hydroxyacyl-CoA dehydrogenase 4) β-ketoacyl-CoA thiolase. Each cycle of the pathway shortens the fatty acyl-CoA chain by two carbon units.
Enzymes make up large and diverse groups of biologically active proteins that are essential for metabolic function in cells. They are very specific and only work on special molecules known as substrate. They form an enzyme-substrate complex that serve as catalyst with the ability to speed up chemical reactions that would otherwise take place too slowly for the body to benefit; enzymes provide an alternative reaction pathway of lower activation energy. Therefore understanding the kinetic behaviour of an enzyme provides clues to its possible physiological role1.
The structure of an enzyme is made in such a way that it would have the function of acting as a catalyst for chemical reactions. Even in modern day Enzymes are being used to help improve the health of individuals. A report in natural news, Written by PF Louis, talks about some functions of
An enzyme can be regarded as a catalyst for a biochemical reaction, or more simply, a biological catalyst. Its sole purpose is to increase the rate of a reaction, or speed up the reaction via provision of an alternative reactive pathway, which entails a lower activation energy. Enzymes participate in the reaction itself, enabling the occurrence of an alternate pathways of reaction, but they do not attain permanent changes to their structure or nature, and as a result remain unchanged preceding a reaction. It is then understood, that they can amplify the rate of a reaction, but are unable to effect upon the equilibratory position. Enzymes, unlike chemical catalysts are highly specific in terms of the reactions that they catalyse.
