Enzymes are protein‚ they are used to catalyse metabolisms in all organisms. They break down complex molecules and build up complex molecules from simple molecules‚ these two processes are catabolic reaction and anabolic reaction respectively. Enzymes are needed in these two processes to catalyse releasing and taking up ATP molecules. Different sequence of amino acid produces different structure of protein‚ which determines the property of protein‚ thus each kind of enzymes has its unique active

Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

An enzyme rotates around the double helix unwinding and flattening the structure. The double helix being unwinded is not a natural shape to have for dsDNA. Once the dsDNA is “unzippered”‚ ssDNA can only have new nucleotides partnered with it in one direction. each strand of the chromosome serves as a template to specify as a new complementary DNA strand. Dna acts as a template because each strand becomes a daughter strand by pairing the bases. Replication happens when the helicase attaches and breaks

compare the action of a catalyst (enzyme) under different environmental conditions. This was determined by performing a variety of different experiments. The first experiment was performed by adding hydrogen peroxide to sand. Due to the fact that the sand was not soluble in the hydrogen peroxide‚ no reaction thus no catalyst were present. Manganese dioxide was also added to the hydrogen peroxide creating a moderately fast reaction thus leading to believe that an enzyme was present to lower the activation

If the temperature is increased‚ the molecules will gain kinetic energy allowing them to move a lot more frequently. Enzymes begin a reaction when they randomly collide with the substrate molecule‚ this is where the enzyme will react upon. The speed and frequency of these collisions is dependent on the temperature‚ so an increase in temperature will effectively increase the rate of reaction and allow more products to be made. Consequently‚ an increase in the temperature will make the vibrational

Effects of Sucrose Concentration On Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy

understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could be determined by testing the pressure in

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

in Gelatin Abstract: For this inquiry lab‚ the research team tested the gelatin solution for the presence of biomolecules. The team searched for the presence of starch‚ glucose‚ lipids‚ and proteins through the use of indicators: Sudan III‚ Lugol’s iodine‚ Benedict’s solution‚ and Biuret’s reagent. After testing the gelatin solution in the presence of the indicators‚ the results showed that Lugol’s reacted‚ turning orange-pink (oils) and the Biuret reagent (protein) reacted with the gelatin solution
