Questions & Step-by-Step Solutions

What is the main function of the light-harvesting complexes?
Correct Answer: Light-harvesting complexes absorb and transfer light energy to the reaction center.
  • Step 1: Understand that light-harvesting complexes are found in plants and some bacteria.
  • Step 2: Know that these complexes contain pigments, like chlorophyll, that can absorb light.
  • Step 3: Realize that when these pigments absorb light, they capture energy from the light.
  • Step 4: Learn that this absorbed energy is then transferred to a part of the cell called the reaction center.
  • Step 5: Understand that the reaction center uses this energy to start the process of photosynthesis.
