when oxygen is not present
Fermentation and the Krebs cycle typically do not occur at the same time in cells. Fermentation is an anaerobic process that occurs in the absence of oxygen and produces lactic acid or ethanol as byproducts. The Krebs cycle, on the other hand, is an aerobic process that requires oxygen and takes place in the mitochondria to produce energy in the form of ATP.
Without oxygen, the electron transport chain cannot function properly to accept electrons from the Krebs cycle. This leads to a buildup of NADH and FADH2 molecules, halting the Krebs cycle. As a result, cellular respiration cannot produce ATP efficiently in the absence of oxygen.

Inhibition of key enzymes in the Krebs cycle, depletion of substrates or cofactors, or inhibition of mitochondrial function can stop the Krebs cycle. Additionally, disruptions in cellular respiration, such as oxygen deprivation or mitochondrial dysfunction, can also halt the Krebs cycle.

First stage is the priming stage, where the Sugar is turned into pyruvate in ten complex steps... This pyruvate goes into the Krebs cycke and with help from oxygen releases ATP molecules. Read more on Kreb's cylce for more..

Kreb's cycle is part of cellular respiration, it needs nothing but oxygen and glucose. Only photosynthesis needs light.
No, the Krebs cycle is aerobic, meaning it requires oxygen to function.
