krebs cycle

why is the krebs cycle considered aerobic when no oxygen is involved in any reaction in it??

Pyruvate can not enter mitochondira and turn into Acetyl CoA without O2.

Indeed O2 is involved in many more ways that you think in the krebs cycle. Never forget that when you look at the cycle there is casacades of reaction between every molecule. Some of those reactions are oxydoreduction. It is a process in wich electrons are passed from a molecule to another that has a stronger electronegativity potential. The last electron accepting molecule is the O2. :)
