38- List two factors that can affect the rate of an enzyme-catalyzed reaction.  No need for a paragraph, or even two sentences.  Just the factors.

Label the diagram on the following slide: • 1. substrates • 2. products • 3. energy of activation without enzyme • 4. energy of activation with enzyme • 5. Which has more energy in this reaction, the substrates or the products? • 6. What happens to the difference in energy during the reaction How does an enzyme make go aster? a chemical reaction A+8 -→C+D A+B Energy Ccakres) CtD Time (min)

The above diagram illustrates ___? The relationship between the proteome and the metabolome The relationship between the concentration of enzymes and the rate of chemical reactions they catalyze a and b

Which statement is true about a reactant that appears in the balanced equation for a reaction but does not appear in the rate equation? a. It is an inhibitor. b. It is not part of the reaction. c. Its concentration is too low to be important. d. It takes part in the reaction after the rate-determining step.

This graph shows the rates of reaction in a chemical reaction with and without the addition of an enzyme.  Explain the shape of each line. What is happening to the reaction rate as the reactant concentration  is changed?  Explain what the enzyme appears to be doing.  What type of enzyme is this?    Why does the curve of the reaction with enzyme flatten out?

Please help answer both questions

Please make sure that the answer you send me is 100% correct thank you 

Add a curve to the graph showing how it would be changed when catalyzed by an enzyme. (No need to submit your drawing). Using the same numbering system as the original figure, select the number(s) that would now have different values in your picture. 1 2 3 4

What chemical reaction is being catalyzed in this experiment? Label the substrate(s), enzyme and product(s). Based on the information in the data table and your graph, is there an optimum temperature for catalase that makes it the most productive in terms of reaction rate? If so, what is the temperature? 3. At what temperature, does the rate of the reaction decrease? Explain why.
