With all these H+ ions built up in the periplasmic space we make our way to a large protein complex just ahead in the membrane. As we get closer we can see that H+ ions are following through this complex and causing it to spin. The energy produce by this spinning is enough to add an inorganic phosphate group to ADP molecule. Some decides to start counting the H+ ions and notices that for every 10 that flow through this complex 3 ATP are made and every 6 that follow through produce 2 ATP.
- What is this process called?
- What is the name of this large complex?
Now that we have reach the end of this process lets summarize our journey through glucose metabolism.
- How many net ATP per glucose were made through substrate level phosphorylation?
- How many total NADH were produced?
- How many FADH2 were produced
- How many ATP were produced via oxidative phosphorylation
- What is theoretical maximum ATP yield for 1 glucose molecule?
Homework Answers
The process is called chemiosmosis or oxidative phosphorylation
Name of the large complex is ATP synthase
Only 2 ATP are made by substrate level phosphorylation
From glycolysis to TCA total 10 NADH (2 in glycolysis, 2 when pyruvate oxidized into acetyl CoA and 6 in TCA from 2 acetyl CoA molecule) are produced
Only 2 FADH2 are produced in TCA from 2 molecules of acetyl CoA
A total of 38 ATP are produced by oxidative phosphorylation
Maximum theoretical yield for 1 glucose is 38 ATP.

Threonine is converted to succinyl CoA through a process that produces 1 molecule of ammonia and 1 NADH while requiring 1 ATP. Consider that the resulting succinyl CoA can use a portion of the citric acid cycle to be converted to oxaloacetate. 1.

Ignore question 4.
1. Calculate the number of ATP produced per carbon atom for a molecule of glucose under oxidative phosphorylation (remember we use as a rule of thumb 2.5ATP per NADH and 1.5ATP per FADH2 based on the number of protons pumped in the ETC). 2. Calculate the number of ATP produced per carbon atom for a saturated fatty acid between 12 and 18 carbons long (make sure you clearly indicate the length of fatty acid you choose, e.g...

Now that we have made it through two redox reactions we wonder what might be coming next. One off our classmates notices we have a phosphoryl group attached to our succinyl-CoA ride. Someone points out that this is a perfect time for another substrate level phosphorylation and indeed the next reaction does just that. What was produced from this substrate level phosphorylation? We now notice just how close we are to the cytoplasmic membrane. In fact we can even see...
