Given the data presented above‚ there are not clear conclusions that can be drawn. In Table 4‚ there is information regarding the effects of varying the concentration of a substrate‚ in this case the pea extract. To view the graphical representation‚ which more clearly displays the relationship‚ view Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute

purpose of this experiment is to study how enzyme activity is affected by environmental conditions. Researchers tested the level of potato extract enzyme activity with 1-11 pH‚ varying temperature‚ catechol solution‚ hydroquinone solution‚ and different measurements of catechol. In Figure 1A and 1B‚ pH levels were tested with potato extract to see how pH would affect the amount of Benzoquinone is formed in the potato. Although it was hypothesized that enzymes would form Benzoquinone better in acidic

Anthony Young Partner: Nick Dale TA: Alekhya 6/15/15 The SN2 Reaction: Factors Affecting SN2 Reaction. Introduction In the substitution reactions‚ the leaving group from the substrate is replaced with the nucleophile. Because of the nucleophile it is called nucleophilic substitution. The lone pair of electrons‚ present on the nucleophile is used to create a new bond with the carbon atom‚ from which the leaving group was separated. There are two different mechanisms of nucleophilic substitution: SN1

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

Factors Affecting The rate of Enzyme Activity Prediction: As the temperature increases the rate of enzyme activity will also increase‚ thus increasing the rate of reaction. However‚ if the temperature is too high the enzyme will denature. Materials: 4 test tubes 2 small beakers A dozen filter paper disks Test tube rack Hydrogen peroxide (H2O2) Potato extract Forceps Thermometer Hot plate Large beaker Ice cubes Graduated cylinder Stopwatch Procedure: Step 1 Place 10 mL of potato

living organism depend on catalytic proteins called enzymes‚ these compound are responsible for metabolism and biochemical regulation of energy‚ there are millions of enzymes and hundreds of enzymes have been identified in the human body as well. All living system possess enzymes as vital components of the body‚ enzymes are found in all organisms. Everyone has a natural pH balance in the body. Enzymes are complex proteins which speed up chemical reactions if this did not happen it would occur to slowly

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added

Jolly Nguyen 11C Conditions needed for effective enzyme action Aim: To investigate the activity of enzymes and how might the activity be effected in different conditions. Hypothesis: Temperature rises and change of substrate concentration may cause denaturation of the protein of enzymes. So as the temperature rises the amount of active enzyme progressively decreases‚ and the rate is slowed. Exposure to heat causes atoms to vibrate violently and this disrupts bonds within globular proteins

Abstract: Enzymes are specific-type proteins that act as a catalyst by lowering the activation energy of a reaction. Each enzyme binds closely to the substrate; this greatly increases the reaction rate of the 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)

and the reproductive cycle with flowering and pollination is completed under water. Seagrasses have a number of adaptations to the submerged life form (Borum et al‚ 2004). Thalassia hemprichii is common on mud-coral-sand or coarse coral-sand substrates‚ in sheltered habitats in the Philippines. The plant has been observed growing from the base and through fingers of corals at 6 m deep. T. hemprichii may be found mixed with Syringodium isoetifolium‚ Cymodocea serrulata‚ C. rotundata‚ Enhalus acoroides
