INTRODUCTION: An enzyme is a substance that in most situations‚ is a catalyst‚ which increases the rate of reaction by contributing alternative reaction pathways of lower activation energy. Enzymes are able to do this by binding to reactant molecules and allowing them to cooperate in a more energy efficient way. If catalyzed by the appropriate enzyme‚ reactions that would take an extreme amount of time would rather occur in fractions of a second. First‚ enzymes increase the rate at which chemical

Growth Growth and development are the most fundamental characteristics of all living organisms. The physiological definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral

Name: Madison Gullatt Sect/Table: !/D Experiment 8 Report: Extracellular Enzymes Purpose: The purpose of this experiment is to perform a variety of different test and record the data from each test in relation to extracellular enzymes. Results: 1. Fill in the following tables with your observations. Note if the test is positive or negative for the enzyme. Also note the appearance of the colonies and/or media. This will include: the color of the medium immediately surrounding

Greek Yogurt Health Benefits In general‚ almost all yogurt varieties are said to be healthy for their nutrient content‚ presence of beneficial bacteria‚ and low levels of lactose. However‚ regular use of sugary and flavored types is not recommended. In case of Greek yogurt‚ the method of preparation itself explains some of its nutritional facts. In other words‚ it can be said that the straining process makes this dairy product a concentrated form of nutrients. The protein level

1. Introduction This chapter deals with overview‚ objectives‚ methodology‚ sampling plan and limitations of the study. 1. . Overview of the study Business analysis of whey in India is not restricted to its well defined boundaries. Because of the nature of the product and its current status‚ it is traded globally and very small quantity is traded within the country. The study is intended to study the effect of global changes on trade. Similarly the emphasis is laid on the application of

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

DNA Extraction Lab Problem Statement: Do you think you have ever eaten DNA? Background Information: DNA is too small to see under a regular microscope‚ so how can it be studied? DNA is a large molecule found in all living things; therefore it is possible to extract it from cells or tissues. All we need to do is disrupt the cell’s plasma membrane and nuclear envelope‚ make the DNA clump together and - voila! - DNA extraction is possible. DNA extractions from onion‚ bananas‚ liver‚ or wheat
