Answer:
This question is incomplete as it lacks options, however, it can be answered. The answer is:
CARBON DIOXIDE (CO2)
Step-by-step explanation:
Cellular respiration is the process by which glucose is broken down in an organism's cell to release energy. Although the process involves series of reactions, however, the general equation is as follows;
C6H12O6 + 6O2 ➡ 6CO2 + 6H2O + energy
Based on the above equation, the inputs are glucose and oxygen while the outputs are carbon dioxide and water. Carbon dioxide (CO2) is the major byproduct of the respiration process.
