Explain the use of enzymes in food production by means of examples. You must include the example of lactase. Enzymes are proteins that speed up the rate of chemical reactions (up to a million times) in living organisms. Acting as catalysts they are not consumed nor altered in the process of converting the specific set of reactants into specific products. In food production‚ enzymes are greatly appreciated by their accelerated effect in biochemical processes and are mostly used in what we

Enzymes are responsible for multiple reactions that take place naturally in the living organisms. The purpose of the enzymes lab was to investigate how the enzymes play a role in a reaction‚ affecting the rate of reaction (ROR). Interestingly‚ we tested how the enzymes affect the reaction rate at multiple temperatures (0‚ 23‚ 37‚ 50‚ 70‚ and 95 C). It was predicted that an increase in temperature will elevate the thermal activity of substrate which increases the chances the substrate molecules will

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

purpose of this lab was to determine the effects of changes in variables such as temperature‚ pH and concentration on catalase enzyme activity. Proteins are organic compounds made up of amino acid subunits consisting of carboxyl and amino functional groups‚ linked together by peptide bonds through condensation reactions. They are an essential part of all living organisms. Enzymes are “biological catalyst used to speed up chemical reactions (Athanasopoulos‚ 2014). Normally‚ for chemical reactions; “reactant

predictions as to how these deficits will manifest by drawing an important distinction between performance effectiveness and processing efficiency. Effectiveness refers to the quality of task performance indexed by standard behavioral measures (generally‚ response accuracy). In contrast‚ efficiency refers to the effort or resources spent in task performance (generally‚ reaction time and spent mental effort)‚ with efficiency decreasing as more resources are invested to attain a given performance level (Eysenck

The free land is not free The author of “In the Land of Free”‚ Edith Maud Eaton‚ with pen name Sui Sin Far‚ was not a direct immigrant from Asia to the United States‚ but she portrayed the harsh treatment Asian immigrants faced upon entering in the U.S. in the late 1800s. Sui Sin Far‚ working as a journalist for Fly Lea‚ had exposed the extreme injustice done to Asian Americans in U.S. while she was living on the west coast of the United States. In addition‚ Sui Sin Far’s narration throughout “The

Dana Calderone Responses of Enzyme Activity from pH and Concentration Abstract Enzymes are the key to many of the chemical reactions that our bodies depend on to live. Without enzymes‚ we would not exist. These biological catalysts speed up the reactions as well as reduce the amount of activation energy needed to complete the process. Knowing how important enzymes are to us‚ it is important to realize what they require to function. They need select conditions and rates to work right. These conditions
