AS substrates are initially added, the activity is higher and then it reaches a plateau with increase. NO. Sucrase activity reached a plateau. Correct Predictions: Optimal temperature: 40 °C (104 °F), Sucrase activity increases with increasing sucrose concentration until a plateau is reached. Incorrect predictions: Sucrase will have highest activity at ph 6 not ph 7 Warm up exercise increases body temperature making it ideal for enzyme activity Increasing myosin activity makes muscles tougher and stiff and limits free movement for performance.
The greater increase in production means more supply than is demanded, therefore the price will decrease. 4. Why did elemental sulphur experience such a large increase in value but not production? This is because of the demand of sulphur is greater than its supply; therefore, the price/value of sulphur increase greater than its production. Sulphur is used mostly for fertilizers, which this significantly contributed towards the increase of production.
The selling price would only increase because the absolute value of -2.5 is 2.5 which are greater than 1 meaning it is elastic and an increase in price leads to a reduction in total revenue. So, to increase total sales revenue, the firm should lower the selling price. b. What happens to the demand for beer if the price of soda falls by 2%? Explain your answer.
Energetics Aim: To measure the energy released from the complete combustion of a known mass of alcohol or paraffin wax, to heat water. Hypothesis: The combustion of alcohols is exothermic. In this experiment the energy is released from burning a known mass of alcohol in order to heat a known amount of water. A comparison of various alcohols and paraffin wax (methanol, ethanol, propanol, butanol, octanol and candle) as fuels can be made by calculating the quantity of energy transferred to the water. In this experiment, the amount of energy (heat) involved in a chemical change will be determined.
Background: A reaction rate is the decrease in concentration of a reactant or the increase in concentration of a product with time. Thus, the units for the reaction rate are usually Molarity per second (M/s) – that is , the change in concentration (measured in molarity) divided by a time interval (seconds in this case) (Chemistry: The Central Science, P. 527). Rate is usually calculated by taking an average of the disappearance or appearance of a compound with respect to time. In this case it is calculated by the absorbance of the light. Reaction rate is affected by any catalysts present (which speed up the reaction usually with an intermediate step), temperature (increases the number of particles collisions), concentration (increases the number of collisions), and surface area (increases the space available for collisions).
The metal always had a larger change in temperature than the water, no matter whether the metal started hot or cold. This is because the metal has much less mass than the water in each trial. In general, the part of the system with less mass will change temperature more. 2. Of the four trials, transfer to the first row of this column the data for the trial that came closer to the theoretical value: | | | | | | Best Case | 80.0 g | 285.1 g | -75.1 C° | +1.9 C° | 0.377 |

a. Reduction in price will cause the contribution margin to decrease, thus, breakeven point will increase. b. Increase in Direct Labor cost will increase the cost and will cost the contribution margin to decrease, thus, the breakeven point will increase. c. Installation of new ventilating equipment produced depreciation (fixed cost) which will decrease contribution margin, thus the breakeven point will increase.
Was the rate of increase of sucrase activity higher at a pH of 8.5 or a pH of 5.5? 3. State the optimum temperature for sucrase activity, and describe how sucrase activity changes at lower and higher temperatures. The optimum temperature for sucrase activity is 40˚ C. Sucrase activity drops at lower and higher temperatures (it kind of levels out with minimal change at higher temperatures but is still dropping). See Table 3: Effect of Sucrose Concentration on Sucrase Activity See Graph: Effect of Sucrose Concentration on Sucrase Activity 4.
Stephen Simpson Access Med 2014 Cell Respiration “Micro-organisms” Abstract Cellular respiration is the process of obtaining energy from food, glucose is oxidised which produces ATP. The experiment was carried out to identify which Carbohydrate molecule was the most efficient for the respiration process, if respiration was taking place and to compare the respiration rate of the micro-organism yeast when conditions are changed. Five test-tubes were labelled A to E, rezasurin dye was placed in each test tube, to which fresh yeast was added, a carbohydrate was then added to test tubes A-D, in A glucose was added, B lactose, C Sucrose, D Starch and in E distilled water was added as a control for the experiment. All five test tubes were placed in a water bath at 35°. The colour change was monitored over a period of 20 minutes and changes recorded every 2 minutes.
