Based on the descriptions here, what has happened to the narrator? Referring to “The premature burial”

In "the premature burial", the narrator is buried alive

the krebs cycle and electron transport occur in the mitochondria, though other than that i would need to know more information.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
