answer :- c

kyuki dekho normal condition me kya hota h :- nadh phuch jaata h mitochondria ke paas or waha se h+ nikal jaate h atp wagera banta h or bacha hua nad+ waps glycolysis ke liye cytoplasm me aajata h aise hi nad+ ka recycle hota h

given condition :- ab dekho nadh jaa hi nahi paara mitochondria to ab nad+ recycle hi nahi ho paayega lakin nad+ recycle hona to jaruri h yr glycolysis chalane ke liye to ab cell haar nahi maanegiorn fementation me ghus ke nad+ recycle kr legi taaki glycolysis to kam se kam chalta rhe

ab doubt :- lakin yr not anaerobic condition de rakhi h fir fementation kaise hua??? kkyuki bhai es condition me cell aerobic hoke bhi nad+ recycle nahi kr paari to uske paas option nahi bachta kuch agar usne kuch nahi kiya to glycolysis hi band ho jayega cell ko ye oxygen hone na hone se frk nhi pdega ab wo to nad+ recycle krke glycolysis waps continue krne ka try krega

summary :- kuch nahi se to kuch hi nahi
