NEETBotanyRespiration in Plants
What are the end products of the complete combustion of glucose?
Options
- ACO₂ and O₂
- BH₂O and O₂
- CCO₂ and H₂O
- DGlucose and oxygen
Correct answer
C. CO₂ and H₂O
Step-by-step solution
The complete combustion of glucose, which produces CO2 and H2O as end products, yields energy most of which is given out as heat . If this energy is to be useful to the cell, it should be able to utilize it to synthesize other molecules that the cell requires. The strategy that the plant cell uses is to catabolize the glucose molecule in such a way that not all the liberated energy goes out as heat. The key is to oxidase glucose not in one step but in several small steps enabling some steps to be just large enough
