What is the most common electron acceptor in the kreb cycle?
a) nad+
b) fadh2
c) fad
d) citrate
e) nadh

a) nad+

Explanation:

Both NAD+ and FAD as electron acceptor in the Kreb Cycle, but every turn of the citric acid cycle releases two carbon dioxide molecules and consumes three NAD+ to give three molecules NADH (in three different steps) but also consumes one FAD  to produce one molecule FADH2 (in one single step).

Each NAD+ accepts one electron, while each FAD accepts two electrons.

Thus, NAD+ accepts three electrons in total per cycle while FAD accepts two electrons in total per cycle.

answer; /// i believe the correct answer is (thrombocytopenia); (a)

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
