What should the cell be able to do with the energy released from...

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 such that the energy released can be coupled to ATP synthesis
