In step 4 of the citric acid cycle, the reduction of NAD+ to NADH is coupled to the generation of CO2 and the formation of a high-energy thioester bond. The energy of the thioester bond is harnessed in step 5. The energy is used to generate a  

  The mitochondrial ATP synthase consists of several different protein subunits. Which subunit binds to ADP + Pi and catalyzes the synthesis of ATP as a result of a conformational change?  

7. Find the x-intercepts and y-intercepts. Make sure to label your answers and write them as ordered pairs.  

  The citric acid cycle generates NADH and FADH2, which are then used in the process of oxidative phosphorylation to make ATP. The reactions in the citric acid cycle do not utilize oxygen. Yet the citric acid cycle stops almost immediately when O2 is removed. Explain this observation.  

8. Find the domain and range of the function. Write your answers in interval notation.
