CHAPTER 6 ENZYMES Answer two of the questions 13 below 1 Dis

CHAPTER 6: ENZYMES. Answer two of the questions 1-3 below. 1. Discuss what it means for biological reactants to be in a metastable State. 2. Discuss HOW enzymes lower the activation energy of a spontaneous chemical reaction. 3. Discuss the role of amino acid R groups in the active site of an enzyme, specifically the roles of amino acids most likely to participate in the active site. CHAPTER 7: MEMBRANES: Answer two of the questions 4-6 below. 4. Discuss how and why a cellular membrane is fluid, and what types of physical properties and molecules can change the fluidity of a membrane. 5. Compare and contrast the different types of membrane proteins, including physical properties that allow them to be maintained in their membrane position. 6. Discuss the concept of a lipid raft, including physical properties organization, and purpose

Solution

1). Metastable states are the high energy states of the molecules, which have short life span. The metastable nature of the reactant molecules is often relies upon the activation energy and if it is high then the proportion of energy is low so that these reactant molecules are highly reactive but have no stability under stable nature.
