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...

Bunsen Burner Hydrochloric Acid
762 wordsThe Problem: I am going to find out how temperature can affect the rate of reaction. Background information: Factors that change the rates of reactions are: ? Temperature? an increase in temperature will make the reaction occur faster. This happens because the particles of that substance move faster when it is heated. Because the particles move faster, they would collide more, making the reaction rate faster. ? Concentration? the increase in concentration, the greater and faster the reaction. Th...
