An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1,000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below.

“Enzymes are proteins that have catalytic functions” [1], “that speed up or slow down reactions”[2], “indispensable to maintenance and activity of life”[1]. They are each very specific, and will only work when a particular substrate fits in their active site. An active site is “a region on the surface of an enzyme where the substrate binds, and where the reaction occurs”[2].

Which gas, oxygen or hydrogen, was produced by the reaction? The hydrogen made the stick pop and the oxygen made the glowing end flare up.

1. When there are two or more reactants involved in a reaction, the active site of the enzyme helps to orient the substrate. Without the catalyzation of an enzyme, the creation of a desired reaction between two substrates is very random and can take longer to occur. The enzyme provides a place where the two substrates can join and perform the desired reaction at a much faster rate that is less random. 2. By bending and putting stress on the chemical bonds of the substrates, enzymes are also able to lower the activation energy needed due to the correlation between the difficulty in breaking bonds and the activation energy.

Enzyme's are important to biochemist, because without them the body could not function

Enzymes are considered to be “biological catalysts” meaning they can speed up a chemical reaction in a cell without being used up in the process. Enzymes do this by lowering the amount of energy needed to activate the process. The lower the activation energy, the faster the reaction. Without enzymes, vital life processes would occur very slowly which could be deadly.

Investigating Enzyme Activity Aim: To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: · pH · Concentration · Temperature · Surface Area pH - Enzymes function at different pH values. In neutral conditions the amount of oxygen gas given of in an enzyme-catalysed reaction will increase. An enzyme is affected by how much acid or alkali is present. Many enzymes work best in neutral conditions but some prefer acids and some prefer alkalis.

Although we might not always acknowledge this small proteins, enzymes have come to be revolutionary when it comes to our survival. This is because enzymes are an example of catalysts, which affect the rate at which a chemical reaction occurs by speeding up. Moreover, this is imperative for our survival because chemical reactions provide the energy required by our bodies to perform several life processes that allow us to carry out many of the activities we perform as part of our everyday life. Thus, an enzyme's ability to function properly has become a major factor in our body's ability to function properly and maintain homeostasis. Unfavorably, however, there are some factors that can negatively affect an enzyme's ability to

Enzymes - are biological catalysts of protein nature, they have the ability to activate a variety of chemical reactions that occur in living organisms. Enzymes produced in any living cell and can be active in and outside the cell. The actions of enzymes strictly specific, only a specific substrate can bind to a specific enzyme. Therefore, the name consists of the name of the substance on which they operate and end with "-ase". For example, an enzyme that cleaves sucrose called sucrase, for lactose - lactase. Enzymes have very high activity. Negligible dose of them is enough to turn huge amounts of substance from one state to another. Enzymes are characterized by certain properties. Certain enzymatic processes are reversible; depending on

As you can see as soon as the lock gets denatured it wll no longer

Page Description: Enzymes play an important role inside the human body and are helpful for treating indigestion. Different types of enzyme supplements are available in the market that are good for the health of patients. Digestive enzyme supplements are beneficial for treating digestive problems but should be consumed in consultation with a physician or a doctor.

Enzymes Enzymes are complex proteins that carry out essentially every chemical reaction in the human body. Enzymes function as biological catalyst, regulating the rate at which chemical reactions proceed without themselves being altered in the process. In this particular experiment we recognized benzoquinone and examined two numbers of factors to determine their effects on enzyme action. The factors were temperature and specificity (how discriminating the enzyme is in catalyzing different potential substrates).

The enzymes inside the human body is a protein molecule which is a biological catalyst containing 3 types of characteristics. The first characteristic of an enzyme is to increase inside the human body depending on the rate of reaction. Secondly most of the enzymes inside the human body will take control and only act specifically upon one reactant, this is called the substrate, and this is the enzyme that produces products. Third most important is the enzymes strongly regulate in a circle, from a low concentration (activity) to a high concentration (activity) then back around vice versa. The enzymes can strongly be affected in the changes of both the temperature and the different ph levels. Every individual enzyme works to a certain extent reacting to a certain ph level and temperature, its activity decreasing at values above and below that point due to denaturation. For enzymes, denaturation can be defined as the loss of enough structure rendering the enzyme inactive. The tertiary structure of the enzymes and their function also includes the non covalent force in creating and determining the shape and the structure of all enzymes. The salivary amylase is found in the salivary glands inside the human body which is produced by the ptyalin. Maltose and Isomaltose are a
