Final answer:
If cellular respiration suddenly ceased, ATP depletion would occur in the cell. Hence the correct answer is option C
Step-by-step explanation:
When cellular respiration ceases, ATP depletion would occur in the cell. Cellular respiration is the process by which cells generate ATP, the energy currency of the cell. Without cellular respiration, the cell would not be able to produce ATP, which is necessary for many cellular processes.
Hence the correct answer is option C
