Enzymes are biological catalysts that speed up chemical reactions, without being used up or changed. Catalase is a globular protein molecule that is found in all living cells. A globular protein is a protein with its molecules curled up into a 'ball' shape. All enzymes have an active site. This is where another molecule(s) can bind with the enzyme. This molecule is known as the substrate. When the substrate binds with the enzyme, a product is produced. Enzymes are specific to their substrate, because the shape of their active site will only fit the shape of their substrate. It is said that the substrate is complimentary to their substrate.

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.

An enzyme is a protein that acts as a catalyst to form reaction, and see the activity of the

Importantly, an administration of 0.9% NaCl or hypertonic NaCl (3 – 7.5% NaCl) also causes corrected hyperchloremia since it contains significantly higher proportion of chloride concentrations compared to sodium concentration ([Na+] = [Cl-] in 0.9% NaCl) than physiologically normal serum concentrations ([Na+] > [Cl-]). Development of corrected hyperchloremia and subsequent metabolic acidosis is also exacerbated by KCl supplementation. For example, 0.9% sodium chloride supplemented with 20 mEq/L KCl has a final chloride concentration of 174 mEq/L ([Na+] < [Cl-]). Experimentally, chronic respiratory alkalosis causes renal chloride retention in dogs, and patients with chronic hypocapnia may be expected to develop corrected hyperchloremia leading to compensatory metabolic

Hypernatremia in Hospitalized Cancer Patients. The purpose of this article was to research the occurrence of hypernatremia in hospitalized cancer patients and the influence it had on the clinical outcomes and healthcare expenses. “Patients with cancer are at high risk of fluid and electrolytes disorders, the common factors related to this include chemotherapy and other anti cancer agents, steroid therapy, surgical procedures, or renal pathology” (Salahudeen, Doshi, & Shah, 2013). The disequilibrium of electrolyte influences and predicts survival in cancer patients. This study aimed to assess the frequency

1b. Enzymes are proteins that act as biological catalysts. A catalyst is something that speeds up a reaction without changing its form. Enzymes speed up reactions by lowering the activation energy of a reaction. The activation energy of a

Enzymes are organic catalysts that speed up chemical reactions within the body. Enzymes are specific for one particular reaction or group of related reactions. Enzymes are large globular protein molecules with one or more indentations on their surface called active sites, an active site is the part of the enzyme that binds to the substrate, the active site has a specific shape that will bind to a specific substrate. For an enzyme to catalyse a reaction the small substrate molecules must temporarily bind to the active sites of the enzymes were the bonds in the substrate are broken and the products released.

Enzymes are catalysts (help process speed) for biochemical reactions. Enzymes are there to speed up reactions by providing the reaction with an alternative reaction pathway of lower energy. Usually, like all catalysts, enzymes always take part in the reaction, as that is how the enzymes provide an alternative reaction pathway. The changes are temporary, so remain unchanged at the end of the reaction. Enzymes are very selective of which reaction can go through, as to catalyzing specific reactions only (M.J. Farabee, 2001).

Enzymes are balls of protein that change a specific substrate into a product by contact at the active site. Enzymes are reusable and once they finish tuning one substrate into a product, it moves on to the next substrate it bumps into in just the right way. The enzyme catalase, which this lab focuses on, can be found in the tissues of plants and animals. Catalase is very important because it takes in hydrogen peroxide, which is toxic to

The biological definition of an enzyme is, a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Based on research in genetics, it can be concluded that there are around 25,000 enzymes. From these enzymes, only 5,000 have been characterized so there is a great deal still to discover. Organic reactions in the body tend to be very slow, so in order to account for the slowness of these reactions, enzymes are needed to be a catalyst in these reactions to speed up the process. Enzymes are binding proteins. They bind with certain substrates to create products.

An enzyme is a macromolecule that acts as a catalyst, a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up energy by lowering activation energy barrier. They break down molecules called substrates.

Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway. But they do not undergo permanent changes and so remain unchanged at the end of the reaction. They can only alter the rate of reaction, not the position of the equilibrium. Enzymes are usually highly selective, catalyzing specific reactions only. This specificity is due to the shapes of the enzyme molecules.

An enzyme is a protein that acts as a catalyst in various reactions. Enzymes are used to help living organisms carry out bodily functions in a timely manner. Enzymes are able to reduce the time it takes for a reaction to occur because they reduce the necessary activation energy. When less energy is required, the process moves quicker. Enzymatic reaction time cab be seen in the human body during digestion. The breakdown of the food we eat is done by enzymes. These enzymes help the body break down food to become nutrients to fuse the body quickly enough that the food doesn’t build up and become toxic to the body. A catalyst is used to speed up a reaction, but a catalyst will only speed up a reaction that is able to process on its own. In other words, a catalyst is not able to create a reaction; it is only able to speed it up. Enzymes are able to be reused many times, so they are recycled in the body. The enzyme reaction is catechol+1/2 oxygenbenzoquinone+H2o, and catecholase is used to yield this reaction. Catecholase is an enzyme that speeds up the reaction that converts catechol into benzoquinone.

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, proteins that act as catalysts, are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes, the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol [2]. In the presence of oxygen, the removal of two hydrogen atoms oxidizes the compound catechol, as a result of the formation of water [2]. Oxygen is reduced by the addition of two hydrogen atoms, which also forms water, after catechol is
