Question

question 8 of 10
in what situation does anaerobic respiration take place?
a. when there is no nitrogen
b. when there is no nadh
c. when there is no oxygen
d. when there is no atp

Explanation:

Anaerobic respiration occurs in the absence of oxygen. It is a metabolic process that allows cells to produce energy (in the form of ATP) without using oxygen as the final electron acceptor, unlike aerobic respiration. Options A (nitrogen is not directly related to the occurrence of anaerobic respiration in this context), B (NADH is involved in both aerobic and anaerobic respiration pathways but its absence is not the trigger for anaerobic respiration), and D (ATP is the product of respiration, not a factor that determines whether anaerobic respiration occurs) are incorrect.

Answer:

C. When there is no oxygen
