18. The rate of synthesis of an enzyme and its concentration directly control the rate of reaction it catalyzes. Answer: True explain

The site on an enzyme molecule that does the catalytic work is called the: a. binding site. b. allosteric site. c. lock. d. active site.

Write a brief description of the relationships among each of the following groups of terms or phrases. Answers to the Concept-Linking Exercises are given at the end of the chapter. Enzyme, enzyme substrate, active site, induced fit model

Match the following enzymes and substrates: Enzyme Substrate a. sucrase b. amylase c. lactase d. maltase e. arginase maltose amylose sucrose arginine lactose

. Describe the lock-and-key model for enzymes. Why are the shapes of the enzyme and its substrate important in this model? What does it mean to say that an enzyme is inhibited by a particular molecule? What happens if this inhibition is irreversible? Can you think of a situation in which it might be advantageous to be able to inhibit an enzyme?

Consider the simple reaction S <--> P, with the forward rate characterized by a rate constant k1, the reverse rate constant characterized by a rate constant k2, and the equilibrium constant for the reaction given by Keq. Which of the listed effects would be brought about by an enzyme catalyzing this reaction?a) increased Keqb) increased k1c) decreased transition state free energy changed) increased k2

13. A specific enzyme will usually only catalyze one particular reacton. True  False

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.

What is the function of the enzyme lactase?

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
