Question

What is the role in photosynthesis of the light-harvesting antenna pigments?

Answer 1

The light-harvesting complex (or antenna complex) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. ... Chlorophyll a is known as the corepigment.

Answer 2

Answer:

1. The antenna pigments' function is to collect light energy from the sun and send it to reaction centres.
2. These pigments can be found in the thylakoid membranes of chloroplasts in green plants and algae.
3. Pigments are found in intracytoplasmic membranes or specific vesicles in photosynthetic bacteria.
4. Chlorophyll a and b in plants, chlorophyll c in certain algae, and bacteriochlorophyll a, b, or c in bacteria are the primary antenna pigments.
5. Carotenoids and phycobiliproteins are examples of accessory pigments.
6. The electronic excitation of a pigment molecule is transported after light absorption until it is trapped by a reaction centre.
