Some cool enzyme (CE) catalyzes the conversion of compound F to compound A. Which of the following must be true of CE? Choice 1 of 4: CE can facilitate conversion of compound A into compound F. Choice 2 of 4: CE binds more tightly to the substrate F than to the product A. Choice 3 of 4: CE decreases the energy of the transition state between compounds F and A. Choice 4 of 4: CE facilitates net conversion of F to A whenever F is present.
Rearrange the following terms to show the process of enzymatic reaction. Use and + to complete the equation. enzyme enzyme-substrate complex enzyme product substrate Several important things should be noted about this reaction: 1. A/an because of the fit between their structures; 2. As a result, something happens to the example, it might be split in two at a particular location. 3. Then the and 4. The enzyme is again. 5. Note that the arrows in the formula for enzyme reaction point acts on a specific to form a/an molecule. For comes apart, yielding the in the reaction and is now free to react _- This means that the reaction is 6. An enzyme-substrate complex can simply go back to the the 7.

I Shown below is a plot of the rate of enzyme reaction to substrate concentration, where a substrate S binds reversibly to enzyme E to form an enzyme-substrate complex ES, which then reacts irreversibly to generate a product P and regenerate the free enzyme E. E+S ES →E+ P For many enzymes, the rate of the reaction increases with substrate concentration, till it reaches a plateau, Vmax because the enzyme is sàturated, or all enzyme molecules are bound to substrate molecules. This is shown below in the graph as curve A. The substrate concentration that gives you a rate that is halfway to Vmax is called the Km, and is a useful measure of how quickly reaction rate increases with substrate concentration. a. Which of the curves B or C Vmax best demonstrates enzyme B. activity in the presence of a competitive inhibitor? Explain briefly why. 1/2 Vmax Vmax -- C b.
