maybe you should ask more specific questions and then we'll try to answer them

Krebs Cycle is another term for the citric acid cycle.
Basically:
the ACETYL-CoA transferrs its two-carbon acetyl group to an oxaloacetate group to form citrate.
The citrate then goes through a series of chemical transformations, losing two carboxyl groups as CO2.
The carbons lost as CO2 are from what was oxaloacetate, not directly from the ACETYL-CoA.
The carbons from the ACETYL-CoA then become part of the oxaloacetate
The loss of the ACETYL-CoA CO2 requires several turns of the citric acid cycle. Because of the role of the citric acid cycle in anabolism, they may not be lost since many TCA cycle intermediates are also used as precursors for the biosynthesis of other molecules.
Most of the energy made available by the oxidative steps of the cycle is transferred as energy-rich electrons to NAD+, forming NADH. For each ACETYL group that enters the citric acid cycle, three molecules of NADH are produced.
Electrons are also transferred to the electron acceptor Q, forming QH2.
At the end of each cycle the oxaloacetate has been regenerated, and the cycle continues.
