In the Krebs Cycle (also known as the Citric Acid Cycle or TCA Cycle), the primary electron carrier molecules produced are:

- **NADH**
- **FADH2**

So, the correct selections from your list are:

- **FADH2**
- **NADH**

NADPH is not produced in the Krebs Cycle (it is produced in the photosynthesis process), ATP is generated as well, but it is not an electron carrier molecule.
