Question
Which molecule is produced during the light reactions of photosynthesis?
- O2
- ADP
- CO2
- C6H12O6
Solution
The molecule that is produced during the light reactions of photosynthesis is O2 (oxygen).
Here's a step-by-step explanation:
-
Photosynthesis is a process used by plants and other organisms to convert light energy, usually from the sun, into chemical energy that can be used to fuel the organisms' activities.
-
This process consists of two stages: the light-dependent reactions (light reactions) and the light-independent reactions (Calvin cycle).
-
During the light reactions, which take place in the thylakoid membranes of the chloroplasts, light energy is converted into chemical energy.
-
Water molecules are split in the process, releasing oxygen (O2) as a waste product. This is the only part of photosynthesis that produces O2.
-
The other molecules listed (ADP, CO2, C6H12O6) are involved in photosynthesis, but they are not produced during the light reactions. ADP and CO2 are used in the Calvin cycle to produce glucose (C6H12O6), and the ADP is then recycled back into the light reactions.
