Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. 61656; The surface area, the bigger t...

Rate Of Reaction Hydrochloric Acid
1,993 words4 Results for temperature and concentration on Tables 5 Graph for results for rate of reaction against temperature 6 Graph of results for rate of reaction against time 8 Graph and table of typical results This investigation is about Rates of Reaction and what affects them. In this case I am going to look at hydrochloric acid and sodium thiosulphate, which is a precipitation reaction. I will be investigating whether a change in temperature affects the rate of reaction. Sodium thiosulphate and hyd...

Concentration And Reaction Rate
1,776 wordster> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Investigation On The Enzyme Trypsin
2,197 wordsAn Investigation determining a factor affecting the rate of digestion of gelatin by the protease trypsin. Introduction An enzyme is a biological catalyst, which speeds up reactions. An example of this in the human body is trypsin (a protease produced in the pancreas and used in the stomach), which catalyses the digestion of gelatine, a protein. For this investigation, a photographic film will be the source of the gelatine. I will be able to identify when the gelatine is digested, when the photog...

Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Without enzymes toxins would soon build up and the supply of respiratory substrate would decrease. ? Enzymes are proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyst? one enzyme will react with molecules...

Digestive Enzymes Kinetic Energy
788 wordsIntroduction Enzymes are Enzymes Enzymes Essay Introduction 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 catalyst, or spark, the reactions within the cells. The bodys organs, tissues and cells are r...

Carbon Dioxide Measuring Cylinder
3,019 wordsAim 1 To find Fermentation Aims Aim 1 To find out what factors affect how quickly bread dough rises. There are a number of factors that affect how quickly bread dough rises. These are: · Amount of sugar-if the amount of sugar is increased, the rate of reaction will increase. Adding a higher concentration of sugar will increase the sugar particles in a given space. As the mixture is heated, the sugar particles will begin to move. Due to a lack of space, this would result in collisions. Thu...

Rate Of Reaction Calcium Carbonate
2,367 wordsInvestigation Into The Relationship Between Temperature Of Investigation Into The Relationship Between Temperature Of Acid And The Rate Of Reaction In The Reaction Of Caco 3 And Hcl Background Information The speed at which reactants are converted into products during a reaction is referred to as its rate. Usually in a reaction, the amount of the product of the reaction is measured to work out the rate of the reaction. In this reaction, the rate will be calculated by the equation: Rate = 1 Time....
