Question

what happens if a cell runs out of oxygen during cellular respiration?
it becomes dormant
it goes through lactic acid fermentation
it undergoes photosynthesis

Explanation:

In the absence of oxygen during cellular respiration, cells switch to anaerobic processes like lactic - acid fermentation to produce energy. Photosynthesis occurs in plants and some microorganisms and requires light, not relevant here. Cells don't become dormant due to lack of oxygen during respiration.

Answer:

it goes through lactic acid fermentation
