- 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. The products of an enzymatic reaction can react with the enzyme to form the and again; 8. It, in turn, may again form the 9. Therefore, the same. and the may act to cause a to go either way.How to differentiate the following simply by seeing the reaction: a. oxidoreductase b. transferase c. hydrolase d. lyase e. isomerase f. ligaseQuestion 23 An enzyme has a single active site at which it can bind and hydrolyze either X or Y but the enzyme cannot bind X and Y at the same time. Which of the following statements are TRUE? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation... SHOW MORE V The Km for X will be affected if Y is present in the reaction mixture. a Y is a competitive inhibitor of X. The Km for X will increase. d. The V for X will be affected if Y is present in the reaction mixture. max pH dependence of Vmax reflects the ionization state of catalytic site e residues. Consider the following: X and Y are methanol (poisonous) and ethanol respectively. If the Km for X = 0.01 M and the Km for Y = 0.001 M then 0.01 M Y is 10 times the concentration of Y required for 0.5 Vmax. Addition of an enzyme to a chemical reaction increases the ratio of g products to reactants (Keg).
