Let me start by answering the final question. Yes, cellular respiration without photosynthesis is possible as long as the oxygen and glucose that cellular respiration requires are supplied via some alternative mechanism.

As the question indicates, photosynthesis and cellular respiration are closely related to each other. The equation for cellular respiration is essentially the equation for photosynthesis backwards.

Photosynthesis occurs within a chloroplast and uses...
