In eukaryotic cells, glycolysis occurs in the cytosol, and the TCA (The Citric Acid) cycle reactions take place in the mitochondria.

Glycolysis is the anaerobic catabolism of glucose which means that its a process in which glucose is broken down to pyruvate, with the production of ATP and NADH.  

The Krebs Cycle, also known as the citric acid cycle is a process in which pyruvate (from the glycolysis) molecules are processed. As a result of 2 cycles (1 for each pyruvate) 24 ATP; 6 NADH + H+, 2 GTP, 2FADH are produced.
