ACTIVITY 10.1
Refer to Model 10. 1 and answer the question that follows
1. What is free energy? What is its symbol?
2. For an exergonic reaction, what is the value of AG?
3. For an endergonic, what is the value of AG?
4. What are the factors that affect AG?
5. What is energy coupling? In a coupling reaction, what must be the
overall value of AG?
6. What does the cell do with the energy produced from exergonic
reactions?
7. What molecule does the cell use as an energy carrier? Draw its
structure.
8. Why is it that this energy carrier is considered to be high energy
containing phosphate?
9. Bond of this energy carrier of cells is broken through what?
