The Effect Of Enzymes On Enzyme And Substrate

Enzymes are biological catalysts, which means it decreases activation energy in reactions. The lower activation energy in a reaction, the faster the reaction rate. Many enzymes alter their shape when they bind to the activation site. This is called induced fit, meaning for the enzyme to work to its full potential it has to change shape to binding substrate. The location of enzyme’s activation site is on the surface of the enzyme, where the binding of substrates take place. Enzyme activity can be influenced by a variety of environmental factors. If the concentration of enzyme is low, and there is a great deal of substrate, then increasing enzyme concentration results in more molecules available to convert substrates to products. Thus, increasing enzyme concentration can increase reaction rate. If substrate concentrations are low, and many of the existing enzymes are idle because of a lack of substrate, then adding enzyme will have no effect on reaction rate. Enzyme concentration affects the enzyme activity, because the more enzyme concentration the faster the reaction rate, until it hits it’s limiting factor. When substrate concentration is increased, it also increases rate of reaction. Temperature plays an important

Enzyme catalysis is dependant upon factors such as concentration of enzyme and substrate, temperature and pH. These factors determine the rate of reaction, and an increase in temperature or pH above the optimum will

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.

Question: How does changing enzyme concentration or temperature affect the reaction time of enzyme activity?

Enzymes are a very important to the biological process. Enzymes help break down food and are essential in helping convert that food to energy. Enzymes have a single function, which makes them unique and need specific conditions in order for the reaction to occur. Every function in an organism has its own unique enzyme (What are enzymes?). One important thing to know about enzymes is that they are proteins. According to rsc.org enzymes are efficient catalysts for biochemical reactions and they, “speed up reactions by providing an alternative reaction pathway of lower activation energy” (Enzymes).

• Enzymes are involved in processes such as the breakdown of carbohydrates and converts them into energy for the body to use.

Temperature affects the rate of which the enzyme reacts, enzymes react typically faster in hotter temperatures than colder. Ph levels that are extremely low or high can stop enzyme activity completely or slow them down.If there is more enzyme concentration the reaction is quicker because enzymes become constant. Also if substrate activity increases, so the reaction time speeds up until maximum is reached.

The motive of this lab is to attain a better understanding of enzyme activity by timing chemical reactions in certain temperatures and pH levels. Enzymes act as catalysts that help speed up reactions. Without these enzymes chemical reactions in metabolism would be backed up. There are two factors that affect an enzyme’s reaction rate: temperature and pH levels. In this label we will be testing different pH levels and temperatures to see which ones cause the most reactions.

Enzymes are biological catalysts, which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats, carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes, most physiological processes would not take place. Hundreds of different types of enzymes are present in plant and animal cells and each is very specific in its function.

What is an enzyme? An enzyme is a biological catalyst that can speed up a chemical reaction by lowering the activation energy. Typically the lower the activation energy the faster the reaction will be. It's made up of a plethora of different types of proteins that forms into a 3D like shape. Enzymes are very important to the human body, because it keeps the chemical activity that undergoes in our body at a low temperature.

Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department, 2011).

Introduction: Enzymes are essential protein molecules that are used by living organisms to survive (Appleby 2014). They perform chemical reactions with such efficiency that life in the cell is sustainable (Appleby 2014). Without the specialized function to speed up chemical reactions quickly, cells would not be able to live. Also, enzymes do get used up after catalyzation. Every enzyme has a spot on its surface called the active site (Appleby 2014).

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.

reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow

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.
