bounded substrate. Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2) the environmental factors that can affect the enzymatic activity. The hypothesis‚ in relation to the enzymatic activity by variables such as the substrate concentrations‚ temperature‚ PH and chemical interactions

What do you want us to bring you back?" Eric thought about it a moment‚ and responded in his low‚ heavy voice. "I’m not hungry right now. Go ahead." "You really should eat!" she yelled back. He didn’t respond. Instead‚ he went into his room‚ mirror in hand. Eric had long been obsessed with the paranormal‚ reading books of ghosts

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

temperature increases‚ the kinetic energy of the molecules increase so they move around more meaning that there are more collisions between the enzymes and substrates molecules and therefore more reactions. pH is a factor because the different types of enzymes work best in different pH environments‚ a change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrates) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the

view or that we can read their mind‚ but we never really know‚ you see‚ we do not really understand another person until we have spent some time with them. We don’t know if they are real until some time has passed. In our gospel today we hear these words: "We have found the Messiah‚" Andrew told Peter after spending the better part of a day with Jesus. Wouldn’t it be great to know exactly how that conversation went? "What did Andrew see in Jesus; hear in Jesus; experience in Jesus; perceive in Jesus

Enzymes lower the activation energy of chemical reactions but they themselves are not consumed or altered when doing so. These catalysts work best at optimum temperatures and pH’s. The temperature and pH at which the reaction occurs the quickest is the ideal condition for the enzymatic reaction. Alpha amylase converts starch into glucose and when starch is combined with I2KI indicator a dark purple solution forms. As the enzyme breaks down the starch the absorbency will decrease. The absorbency is measured

Water Pollution: What You Can’t See Can Hurt You By Kristie Brown Most people have the idea that American waterways are more polluted now than ever in the past‚ but in some ways‚ this just isn’t true. Prior to the passing of the Clean Water Act of 1972‚ point source pollution was actually much worse than it is today. This refers to the type of pollution that enters our rivers through direct drainage pipes‚ and the problem has been visibly decreased all over the country. This may seem like

Abstract This experiment was carried out to monitor the ability of the Barley Amylase Enzyme to effectively break down starch in solutions that are increasing in neutral pH. To do this the experiment was carried out so that tubes containing a reaction solution of the Amylase enzyme and starch were simultaneously mixed. The reactions were then introduced to I2-KI‚ which stopped the reactions‚ at two minute intervals. Each of these trials was repeated three times to ensure proper accuracy. After

Dawn Frost SW 241 In the movie See You in September‚ Lindsey was seeing a counselor for therapy to try to understand why she always has a hard time committing to a relationship. She felt so confused but was starting to see a pattern in her previous actions that might help her recognize what her real problem is. At the end of the session her counselor explained that she was leaving for a month so the next appointment would have to be in September. Mentally‚ Lindsey started to freak out and lose
