SSC CGL 2025 PYQ — Question 44

SSC CGL - 25 Sep 2025 - Shift 2 • General Awareness • Q44

Which of the following complexes is also called a light-harvesting complex?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Antenna complex.

The Antenna complex is also known as the light-harvesting complex (LHC). It consists of a collection of proteins and photosynthetic pigment molecules (such as chlorophyll a, chlorophyll b, and carotenoids) bound to the thylakoid membrane. Its primary function is to absorb light energy (photons) from the sun and transfer this excitation energy rapidly via resonance energy transfer to the reaction center chlorophyll molecules, initiating the light-dependent reactions of photosynthesis.
