Question

What is produced during the Krebs cycle?

CO2, ATP, NADH, and FADH2

Pyruvate, CO2, and ATP

ATP, FADH2, and H2O

H2O, ADP, and NADH

Answer 1

The KREBS cycle turns a sugar molecule into a number of smaller molecules, whose main function is to supply very small packets of energy to cells. There are a number of molecules produced, of which the most common is Adenine triphosphate, aka ATP (which is used to "carry" energy around the body)
This cycle is of first importance to all animals; anything which interferes with the Krebs cycle kills the organism very rapidly.

Thank you, as I thought. This eliminated two options but there are still two that involve ATP.
