I. Preparation A. Choosing 1. You should choose the fruits that you like. a. For example‚ if you desire to gain more different fruits enzymes or make the glass bottle more colorful‚ you can choose four or even more kind of fruits. There is no limitation. But‚ you must include one fruit‚ lemon. It helps to kill the bacteria of the drink. B. Composing 1. The ratio of components should be 3‚ 1. It means 3 parts of fruits‚ 1 part of sugar. You can follow this ratio to determine the amount of fruit

Project Enzymes are organic catalysts produced by living organisms which aid in the progression of specific biochemical reactions without undergoing any permanent chemical changes themselves. They are complex‚ conjugated proteins necessary and required to sustain life. Today‚ enzymes are also used world-wide in a variety of different industrial applications such as the production of paper‚ wine fermentation‚ and bio-remediation. One of the most important industrial applications enzymes are used

Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food‚ for stimulating the brain‚ for providing cellular energy‚ and for repairing all tissues‚ organs‚ and cells. There are three types of enzymes: metabolic enzymes‚ digestive enzymes‚ and food enzymes. Metabolic enzymes catalyse‚ or spark‚ the reactions within the cells. The body’s organs‚ tissues and cells are run by metabolic enzymes. Without them our bodies

on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors. They do not compete with the substrates for the active sites of enzymes. They attach to other parts of the enzyme molecules

I. Aim The aim of the three experiments is actually to investigate the effects of different factors such as temperature‚ pH‚ and concentration of substrate‚ on the activity of the enzymes. By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase

Discovery Restriction enzymes were discovered 40 years ago during investigations into the phenomenon of host-specific restriction and modification of bacterial viruses. Restriction enzymes protect bacteria from infections by viruses‚ and it is generally accepted that this is their role in nature. They function as microbial immune systems. When a strain of E. coli lacking a restriction enzyme is infected with a virus‚ most virus particles can initiate a successful infection. When the same strain
