The Krebs cycle runs twice to break down one molecule of glucose.

two. One for each pyruvate that was made at the end of glycolysis.
Two. One for each of the acetyl-CoA's it generates from glycolysis and pyruvate decarboxylation.

Kreb's cycle is part of cellular respiration, it needs nothing but oxygen and glucose. Only photosynthesis needs light.
The Krebs cycle generates approximately 30 ATP molecules per glucose molecule respired.The actual number varies, because varying amounts of energy are diverted into other processes than ATP synthesis.For a discussion of some of the issues, visit:http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/CellularRespiration.html#citric_acid
