Question
Photosynthesis relies predominantly on light in the visible and near-infrared region of the electromagnetic spectrum. This light is capable of __________.
1. breaking strong, covalent bonds, thus allowing for the generation of different combinations of carbon atoms that ultimately make up carbohydrates
2. reducing CO2 directly in the presence of water as part of the synthetic route to carbohydrates
3. causing transitions in the electronic states of organic molecules that can drive reactions
4. None of the listed responses is correct.
Explanation / Answer
The best answer that fits the quesion is:
3. causing transitions in the electronic states of organic molecules that can drive reactions
Since those electrons are pretty excited, meaning that the chemical moleculaes are easy to react
therefore, CO2 + H2O can overcome ht ethermodynamics and become a real reaction
