Which chlorophyll transfers energy to chlorophyll a?

Explanation

Both chlorophyll b and carotenoids transfer energy to chlorophyll a during photosynthesis. These pigments are known as accessory pigments because they assist in capturing additional light energy that chlorophyll a cannot absorb efficiently. Chlorophyll b absorbs light mainly in the blue and red-orange regions of the spectrum, while carotenoids absorb primarily blue and violet light. The energy they capture is then transferred to chlorophyll a, which uses it to drive the light-dependent reactions of photosynthesis. In this way, chlorophyll b and carotenoids broaden the range of light wavelengths utilized and enhance the overall efficiency of photosynthesis in plants and algae.
