Question

What is the function of the above mentioned pigment?​

Answer 1

Answer:

Explanation:

The main functions of the RPE are the following: (1) Transport of nutrients, ions, and water (2) absorption of light and protection against photooxidation, (3) reisomerization of all-trans-retinal into 11-cis-retinal, which is a key element of the visual cycle, (4) phagocytosis of shed photoreceptor membranes

Answer 2

Their functions include light harvesting, energy transfer, photochemical redox reaction, as well as photoprotection.

Explanation:

The main functions of the RPE are the following:

Transport of nutrients, ions, and water:

• The circulatory system delivers nutrients and chemical messages to the tissues while also removing waste and heat.

Absorption of light and protection against photooxidation:

• As chlorophyll collects light energy for use in photosynthesis, carotenoids serve a crucial role in protecting it from photo toxicity.

Reisomerization of all-trans-retinal into 11-cis-retinal, which is a key element of the visual cycle:

• Isomers are two or more compounds with the same molecular formula but distinct structural formulas.

Phagocytosis of shed photoreceptor membranes:

• The preservation of photoreceptors and consequently vision is dependent on RPE phagocytosis of shed outer segment pieces.
