Chemical Reactions On Metabolic Pathways

Beano’s chemistry, enzymes, and flatulence. During the project it stated that enzymes act like a key and lock mechanism. Enzymes can target specific molecules and only allow certain reactions to take place. There are also rate-determining factors that determine the speed of the enzyme reactions. Since enzymes are catalysts, they are not used up in a reaction; this means that other factors determine the rate of catalytic reactions. Rate of diffusion is a factor that can govern the rate of enzyme activity. Another factor that determines the rate of these reactions is the concentration of the substrate. The principle behind this is that more substrate molecules will increase the frequency of enzyme-substrate interactions. This will eventually

Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is

Enzymes are biological catalysts, which speed up the rate of reaction without being used up during the reaction, which take place in living organisms. They do this by lowering the activation energy. The activation energy is the energy needed to start the reaction.

Metabolism is the word for every chemical reaction that takes place within a living organism. The energy is released from the food by respiration.

Enzymes are defined as catalysts that speed up chemical reactions but remain the same themselves. The shape of an enzyme enables it to receive one type of molecule and that specific molecule will fit into the enzyme’s shape. Where a substance fits into an enzyme is called the active site and the substance that fits into the active site is called a substrate. Several factors affect enzymes and the rate of their reactions. Temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators can all affect enzymes. Temperature can affect enzymes because if the temperature gets too high, it can cause the enzyme to denature. pH can affect an enzyme by changing the shape of the enzyme or the charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. Every enzyme has an ideal pH that it will strive in. Increasing substrate concentration increases the rate of reaction because more substrate molecules will be interacting and colliding with enzyme molecules, so more product will be formed. Inhibitors can affect enzymes and the rate of their reactions by either slowing down or stopping catalysis. The three types of inhibitors include competitive, non-competitive, and substrate inhibition.

Enzymes are proteins that act as catalysts during a biochemical process. Catalysts are non-changing enzymes that can increase or decrease activation energy to accelerate or slow down a biochemical reaction without using additional energy.

Introduction: Metabolism is a term in which defines all of the chemical reactions involving energy production. Some of these chemical reactions involve cellular respiration “by which is the series of metabolic process by which living cells produce energy through the oxidation of organic

Anabolic pathways utilize the energy to build complicated molecules from simpler compounds; these use the energy released by catabolic reactions.

Metabolism is everywhere in our life and constantly happening. Metabolism is the physical and chemical processes in which an organism are produced, maintained, and destroyed which energy is made available. It is needed to maintain life because it allows any living organism to grow, reproduce, repair damages, and respond to its environment. It has two sides Anabolism and Catabolism, which play important roles. Anabolism is a succession of chemical reactions that construct or synthesize molecules that have been broken down by using energy. When catabolic chemical reactions break down complex molecules into smaller units and releasing energy.

The way enzymes work is best described by the lock and key theory. Enzymes have a specifically shaped active site. This active site is highly specific to the shape of the substrate molecules, giving the substrates a surface to react on. This concept consists of the substrate ‘key’ being able to fit into the active site ‘lock’; here the substrate is held in place to proceed with the full reaction. Enzymes work best at their optimum temperatures and therefore homeostasis is important.

There are thousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions occur too slowly on their own. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature of the cell. These catalysts are needed in only very small amounts because a single enzyme molecule can complete the same reaction thousands of times in one minute.

Enzymes are natural catalysts that work from the ability to increase the rate of reaction by decreasing the activation energy of a reaction. (Blanco, Blanco 2017) An enzyme can do this 10^8- to 10^10 fold, sometimes even 10^15 fold. (Malacinsk, Freifelder 1998) The substrate will momentarily bind with the enzyme making the enzyme-substrate complex, of which the shape of the substrate is complimentary to the shape of the active site on the enzyme it is binding with. There are two main theories as to how an enzymes and substrates interact, the lock-and-key model and induced fit theory. The lock-and-key model suggests that the enzyme has a specific shape that fits the substrate and only that substrate. The induced fit theory says the active site and substrate are able to change shape or distort for the reaction to take place with (Cooper,

Enzymes are proteins that act as catalysts and help reactions take place. In short, enzymes reduce the energy needed for a reaction to take place, permitting a reaction to take place more easily. Some enzymes are shape specific and reduce the energy for certain reactions. Enzymes have unique folds of the amino acid chain which result in specifically shaped active sites (Frankova Fry 2013). When substrates fit in the active site of an enzyme, then it is able to catalyze the reaction. Enzyme activity is affected by the concentrations of the enzymes and substrate present (Worthington 2010). As the incidence of enzyme increases, the rate of reaction increases. Additionally, as the incidence of substrate increases so does the rate of reaction.

Enzymes are macromolecules that act as a catalyst, and it’s a chemical agent that accelerates the reaction without being consumed by the feedback or the results (Campbell and Reece, 2005). After the adjustment by the enzymes, the chemical movement through the pathways of metabolism will become awfully crowded because many chemical reactions are taking a long time (Campbell and Reece, 2005). There are two kinds of reactions in nature. The first one is Catabolic reaction and the second one is Anabolic reaction. Catabolic reactions are large molecules that are broken up into smaller molecules (Ahmed, 2013). Anabolic reactions are small molecules that join to make larger molecules, like polymerization (Ahmed, 2013). If you

Metabolism is defined the sum of all chemical reactions which occurs and are involved in sustaining life of a cell, and thus an organism. Metabolism is of the following two types: catabolism and anabolism. In catabolism, molecules break down producing energy
