O Macmillan LearningOne way of expressing the rate at which an enzyme can catalyze a reaction is to state its turnover number. The turnover numberis the maximum number of substrate molecules that can be acted on by one molecule of enzyme per unit of time.

USSE EUSS reaction rate substrate concentration Blue line - Enzyme alone Red line - Enzyme + unknown compound The 4 graphs above represent the change in enzyme kinetics with the individual addition of different compounds that could be categorized as either: allosteric inhibitors, allosteric activators, competitive inhibitors, activators or non-competitive inhibitors. Review the graphs above. Each graph represents the activity of an enzyme and the enzyme + the addition of an unknown compound. By comparing the kinetics of the enzyme alone to the enzyme + unknown, determine what type of compound was added to each of the 4 different solutions to elicit the observed change.
One way of expressing the rate at which an enzyme can catalyze a reaction is to state its turnover number. The turnover number is the maximum number of substrate molecules that can be acted on by one molecule of enzyme per unit of time. The table gives the turnover number of four representative enzymes.

One way of expressing the rate at which an enzyme can catalyze a reaction is to state its turnover number. The turnover number is the maximum number of substrate molecules that can be acted on by one molecule of enzyme per unit of time. The turnover number for an enzyme (per second) is 752 How many molecules of substrate can one molecule of the enzyme act on in 19.2 min?

Two experiments were performed with the enzymeribonuclease. In experiment 1 the effect of increasingsubstrate concentration on reaction velocity was measured.In experiment 2 the reaction mixtures were identical tothose in experiment 1 except that 0.1 mg of an unknowncompound was added to each tube. Plot the data accordingto the Lineweaver-Burk method. Determine the effect of theunknown compound on the enzyme’s activity. (Substrateconcentration is measured in millimoles per liter. Velocity ismeasured in the change in optical density per hour.)
Please handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.
