The correct products of the Krebs cycle (also known as the citric acid cycle) after one molecule of glucose has been fully oxidized (which accounts for two turns of the cycle, since one glucose molecule is broken down into two pyruvate molecules, each leading to one turn of the cycle) are:
- 6 NADH
- 2 ATP
- 4 CO2
- 2 FADH2
So, the correct option is:
6 NADH, 2 ATP, 4 CO2, and 2 FADH2
