The electrons generated from the krebs cycle are transferred to and then are nad / bonded to oxygen molecules nadh/ combined with hydrogen and oxygen to form water nad / shuttled to the electron transport chain

The electrons generated from the Krebs Cycle are transferred to NAD+ and then sent to the Electron Transport Chain.

The Kreps cycle is part of cellular respiration. Cellular respiration takes place inside the mitochondria. The main purpose of the mitochondria is to convert glucose into energy that the cell can use. The Krebs Cycle is a never-ending cycle which keeps on repeating itself to produce ATP and gives off CO2. 

The Electron Transport Chain is the mechanism used by the cell for obtaining energy from sunlight during the photosynthesis process.
