The Effects of Substrate Concentration‚ Reaction Time and Enzyme Concentration on Enzyme Reactions Corey von Ellm-St. Croix Rachael Kwan ID#: 20427841 Matthew Hrycyshyn & Saeideh Mayanloo Biol 130L‚ Section 017 Wednesday‚ 9:30am-12:20pm‚ 151 November 09‚ 2011 A living system controls its activity through enzymes. Enzymes are made from hundreds or even thousands of amino acids connected in a very unique and specific order. Almost all enzymes are proteins‚ except for ribozymes. The chain

Aim: To test the effect of decay in processed foods vs. non-processed foods Hypothesis: The processed foods will last longer than the non-processed foods because they contain more preservatives and artificial ingredients. Background Information: Preservatives are often added to food to prevent their spoilage‚ or to retain their nutritional value and/or flavor for a longer period. The basic approach is to eliminate microorganisms from the food and prevent their regrowth. This is achieved by

Determining the Production of Glucose During Changes in Temperature and pH‚ and Manipulation of Specificity and Cofactors BIOL-1406-SL8 November 16‚ 2012 Abstract Enzymes are biological catalysts. They work by lowering the activation energy needed to initiate a chemical reaction. Enzymes work within an optimal temperature and optimal pH. Enzymes are highly specific for a single substrate. The Enzyme is usually much larger in size than the substrate it binds to. In some cases‚ an enzyme requires

Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

Why does early and forced marriage happen? The causes of early and forced marriage are complex‚ interrelated and dependent on individual circumstances and context. But the practice is driven by these main factors: gender inequality – women and girls often occupy a lower status in societies as a result of social and cultural traditions‚ attitudes‚ beliefs that deny them their rights and stifle their ability to play an equal role in their homes and communities poverty – in families on a low

Effect of Greywater Irrigation on Soil Hydraulic Properties Henry Hartono Gunawan 1 INTRODUCTION The use of Greywater for landscaping irrigations is becoming common as Western Australia is experiencing the water restriction due to the current drought condition and critically low level surface water storage. Hence‚ the reuse of Greywater can utilise the on-site resource‚ conserve the water efficiently‚ and reduce the load on wastewater disposal system. As there is still lack of information

The Detrimental Effects of Soda What is your favorite soda? Coke? Do you know what is in soda? Cutting down on soda can lead to a healthy and better lifestyle. Studies show that soda‚ though it tastes good‚ has many negative effects that outweigh the positive effects. Soda‚ especially diet‚ is detrimental to the health of your body. My cousin ’s teacher did an experiment with coke. She put a tooth in coke and left it for at least a week. The next time they checked the tooth had disintegrated

Water pollution is a serious matter‚ and can be defined as a problem. Poor water quality is just another way of saying water pollution. Water pollution is when one or more substances build up in water to such an extent‚ that several problems for animals and humans develop. Rivers‚ lakes‚ oceans‚ and other inland waters are able to naturally clean up certain amounts of the pollution by dispersing them harmlessly. Water pollution depends on the quantities: how much of the polluting substance is released

aquatic pollution‚ including littering at beaches and coastal areas where harmful or contaminant chemicals and particles are deposited into the ocean. These are only several of the countless ways in which the marine ecosystem can be disturbed‚ but the effects that aquatic pollution has are overwhelmingly harmful and should be taken into consideration. All aquatic pollution contributes to the downfall of marine life‚ either directly or indirectly. For example‚ plastic that has been littered can entangle
