Question
Table below is intended as a means of summarizing the ATP yield during the aerobic oxidation of glucose. Complete the table for an aerobic bacterium. Drag the labels to their appropriate locations in the table. Labels can be used once, more than once, or not at all.Chapter 10- Chemotrophic Energy Metabolism: Aerobic Respiration Chapter 10, Question 7 21 of 21> Table below is intended as a means of summarizing the ATP yield during the aerobic oxidation of glucose.

Explanation / Answer
GLYCOLYSIS: No CO2 yield during glycolysis. 2 NADH is produced. 3ATP per NADH is produced. no FADH is yield during glycolsis. 2ATP is produced from substrate level phosphorylation.
1 NADH after passing through eletron carrier results in 3 ATP.
2 NADH = 6ATP.
So, Max. ATP yield: 6+2= 8
PYRUVATE OXIDATION: 2 molecule of Co2 is produced from each pyruvate. 2 NADH yield from pyruvate oxidation. 3 ATP per NADH is generated. No FADH yield. No ATP from substrate level phosphorylation as it occurs in cytoplasm during glycolysi and in mitochondria during TCA cycle.
1 NADH after passing through electron carrier results in 3 ATP production. So Max. ATP yield: 6 i.e (2NADH results in 6ATP).
TCA CYCLE: 4 molecules of CO2 released during TCA cycle. 6NADH is produced (3 from each cycle). 3ATP generated per NADH. 2 FADH2 is produced during the TCA cycle. 2 ATP is produced per FADH2. 2ATP is generated from substrate level phosphorylation.
1 NADH after passing through electron carrier results in 3 ATP and 1 FADH2 rsults in 2 ATP.
6NADH = 18 ATP and 2FADH2 = 4 ATP
So Max. ATP yiled during TCA cycle: 18+4+2= 24.
