The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature

1. Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and kill fish. biogeochemical cycles are the pathway that chemicals cycle within the ecosystems involving both living and non-living things. Human activities have a direct impact and can cause an imbalance of these chemicals. A few examples of this would be mining and burning fossil fuels‚ this would increase the amount of chemical elements removed from the reservoirs
