previous marriage. I believe I was about three years old when my father passed. At that time‚ Henry became King Henry IV‚ I was left with very little memory of my father and Alfonso was left with no memories. The Spanish nobles at the time did not wish to have Henry as their king and preferred my younger brother Alfonso. Unfortunately‚ Alfonso died during our teen years and never became king. Eventually‚ I was declared Queen of Castile after a long journey including arranged marriages by my brother‚ war

Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Cellular Biology furthers technology-Enzymes in the Dairy Industry Since ancient times‚ enzymes have played an important role in food production. Especially in the diary industry‚ some enzymes are required for the production of cheese‚ yogurt‚ and other dairy products‚ while others are used in a more specialized fashion such as improving texture or flavour of the product. Enzymes are used to catalyze the desirable reactions in industrial processes. Today‚ enzyme applications in such processing get

Enzymes control the rate of metabolic reactions‚ they act as biological catalysts‚ which means they are used but not used up and they also control the speed of the reaction. Enzymes are proteins which means that anything that disrupts this structure such as high temperature or change in pH will affect the enzyme activity. There are many factors affecting enzyme action for example temperature effects them‚ if the Increasing the heat gives molecules more kinetic energy so they vibrate this can then

Animals and Plants Extinctions causes and effects on human Nowadays ‚ animal extinction is a broad issue‚ one that involves the habitats and environments where other species live and interact with one another . Only a minority of people are concerned with extinction in today痴 society‚ while others might argue that it is a small problem because we are beyond the point of evolution and thus don’t really need to rely on other animals at all. According to statistics of scientific research

are some disadvantages in the process of globalization‚ but the benefits that the world receive far outweighs the costs of it. We have to look at the bigger picture to see that globalization has accelerated the advancement of the world and brought us lots of advantages‚ and its role will continue to be important in the future evolution of the world. We will examine this in four aspects‚ economically‚ environmentally‚ socially and politically. Firstly‚ globalization has brought about great leap forward

Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the

Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down hydrogen peroxide
