experiment is to examine the effect that enzyme concentration has on reaction time and the effect that substrate concentration has on enzyme reaction. Enzymes are biological catalysts that catalyze different chemical reactions. In general, enzymes are proteins and they are each specific to specific chemical reaction. In order for enzymes to process properly, they should maintain a specific three dimensional structure. When enzymes function, they combine with their substrates (reactant) to form susbtrate-enzyme

Summary This case study presents about a chemical manufacturing joint venture in China that involves a German parent firm and its Chinese partner. The German firm has conflicts on different aspects with China in terms of industrial safety, business ethics, and the environment. The Chinese however was upset that they cannot use gift, commissions, and other bribes to favorite their customers to gain more potential customers from China. Disagreement has arisen over whether the joint venture should

Types of Chemical Reactions The vast number of chemical reactions can be classified in any number of ways. Under one scheme they can be categorized either as oxidation-reduction (electron transfer) reactions or non-oxidation-reduction reactions. Another completely different but common classification scheme recognizes four major reaction types: (1) combination or synthesis reactions (2) decomposition reactions (3) substitution or single replacement reactions (4) metathesis or double

Catalysts and How They Work How do they work? A common misconception is that catalysts lower the activation energy of a reaction, whereas really, they are using an alternative route of the reaction in order for the bonds of the reactant to be broken with a lower activation energy. The way catalysts situate this ‘alternative route’ is by binding to the reactant molecule and changing the electron configuration so that there is high electron density near the bond that are trying to be broken.

9028 for run C. Also, the percent error in run C at 33.31% was found to be much lower than the percent error in run D at 55.77%, which mean the concentration of run C is more effective than run D. I. Introduction In this experiment the chemical kinetics of the enzyme catalyzed inversion of sucrose was studied. The reaction that we will study in this experiment is the inversion of sucrose, catalyzed by the enzyme invertase that is derived from yeast:
