The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

Effect of Enzyme and Substrate Concentration on Reaction Rate by Zachary A. Poché Biology 155 Laboratory October 15‚ 2014 Lab Partners: Cade White‚ Hannah Ragas‚ Russheka Aremillion ABSTRACT In order to increase the reaction rate‚ substrates attach to the active site of enzymes which decrease the activation energy required to convert substrates to products. We examined the effect of enzyme concentration and substrate concentration on the overall rate of the reaction. To determine
