- Q1In an experiment to determine the effect of temperature on the rate of decomposition by an enzyme, it takes 5 seconds for the indicator to reach the end point. What is the rate of the reaction?0.0250.50.2130s
- Q2A range of equipment and chemicals are used in the experiment to determine the effect of temperature on the rate of decomposition by an enzyme. Match the words with their function in the experiment.Users link answersLinking30s
- Q3At which of the following points are enzymes being denatured?cab30s
- Q4Point b in the graph is known as the enzyme's optimum temperature. Which of the following statements explains what is happening at point 'b'?The active sites of the enzymes are changing as it becomes denatured.The number of collisions between enzymes & substrate are most frequent.There are fewer collisions taking place between the enzyme and substrate.30s
- Q5What is the name of the part of the enzyme that the substrate needs to collide with for a reaction to take place?Users enter free textType an Answer30s
- Q6How does keeping food such as meat or fish in the fridge help to slow the rate of decomposition?The low temperature increases the number of bacteriaThe fridge door prevents oxygen from getting into the fridge.The fridge helps to dry the food.The low temperature of the fridge slows enzyme activity.30s
