NEETBotanyRespiration in Plants
What strategy does the plant cell use to make the energy from glucose useful?
Options
- AStore all the energy as heat
- BCatabolize glucose in several small steps
- CRelease all the energy in one step
- DConvert glucose directly into ATP
Correct answer
B. Catabolize glucose in several small steps
Step-by-step solution
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. How this is done is, essentially, the story of respiration
