survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution. Introduction Enzymes are proteins that catalyze and convert molecules into combinations of other molecules which is necessary for the

graph‚ you can see that there is a relation between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size of the surface

“The Synthesis of Zinc Chloride”‚ what a peculiar name for a lab that does not even involve synthesis. Synthesis‚ by definition‚ is when two elements are combined in a chemical reaction‚but that is not the case. In this lab we are combining zinc‚ an element‚ and hydrochloric acid‚ a compound‚ but combining a compound and an element is not synthesis‚ it is single replacement. We are taking zinc and hydrochloric acid and making zinc chloride and hydrogen‚ a single replacement‚ but what occurred during

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists

solution would be put into the cuvette at precisely 30 seconds and so time would not have an effect on my results. I also used separate pipettes to measure out the starch‚ amylase and distilled water so that the solutions don’t mix together before the reaction should start. Also‚ I repeated each of my experiments two times to make sure I get accurate

of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported into the mitochondrial matrix via active transport. Numerous reactions‚ catalyzed by a multi enzyme complex then occur‚ where the pyruvate is decarboxylated as shown in the reaction below.

area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area increases the rate of reaction increases
