Question

What are the types of photosynthetic pigments that bacteria possess?

Answer 1

Photosynthetic pigments:

1. These are brightly coloured chemicals that reflect the specific wavelengths of visible light.
2. The photosynthetic pigments in plants are responsible for absorbing visible light.
3. These pigments are found in photosynthetic bacteria, algae, and plants.

Types of photosynthetic pigments that bacteria possess:

Bacteriorhodopsin:

1. The photosynthetic pigments are found in the bacteria living in salty areas.
2. The light-driven synthesis of ATP does not involve bacteriochlorophyll instead, a proton is inserted into the bacterial membrane.
3. Rhodopsin is a brown-coloured carotenoid-like protein that absorbs the light in green treason of the visible spectrum and transfers H⁺ across the membrane.

Phycobilins:

1. The photosynthetic pigments are present in the thylakoid membranes of cyanobacteria.
2. Phycobilins are water-soluble proteins that are red, or blue in color that contain linear tetrapyrroles.
