The Role Of Light In Photosynthesis Biology Essay

The first pigments gene to be duplicated, tyrosinase-related-protein-1(Tyrp1), was initially thought to be the gene accountable for the albino rabbit mutant, but albinism was later mapped, duplicated, sequenced and correctly attributed to the tyrosinase locus Together, these loci offer outstanding applicants for learning flexible difference in organic communities of vertebrates....

The main plant pigment involved in the process of photosynthesis is ..

Because different pigments absorb light of different wavelengths, by
comparing the occurrence of different pigments we can deduce the
plants' habitat;

l We can do further experiment to determine the absorption spectrum of
each pigment.

Plant Pigments and Photosynthesis Introduction: ..

Plants use more than one photosynthetic pigment to absorb light. This maximises the use of energy from the Sun. These pigments include:

This was done by separating the photosynthetic pigments (chlorophyll a, chlorophyll b, carotene and xanthophylls) from one another using paper chromatography.

Photosystem II (PSII) is a specialized protein complex that uses light energy to drive the transfer of electrons from water to plastoquinone, resulting in the production of oxygen and the release of reduced plastoquinone into the photosynthetic membrane. The key components of the PSII complex include a peripheral antenna system that employs chlorophyll and other pigment molecules to absorb light, a reaction centre at the core of the complex that is the site of the initial electron transfer reactions, an Mn4OCa cluster that catalyses water oxidation and a binding pocket for the reduction of plastoquinone. PSII is the sole source of oxygen production in all oxygenic photosynthetic organisms, which include plants, algae and cyanobacteria. In these organisms, PSII operates in series with other protein complexes, including the PSI reaction centre, to produce the reduced form of nicotenamide–adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), which is used in the Calvin–Benson cycle to produce carbohydrates from carbon dioxide.

The protein matterincludes some of the enzymes and coenzymes used in the photosyntheticprocess; the lipid portion contains two types of chlorophyll, alongwith other pigments that assist in absorbing light energy.

What role does chlorophyll play in photosynthesis?

Allphotosynthetic organisms--with the exception of a minor group ofbacteria, the halobacteria--contain the light-absorbing pigmentchlorophyll, which plays a key role in the transfer of energy fromlight to chemical compounds.Photosynthesis is the fundamental process that maintains life onEarth.

They serve as accessory light harvesting pigments,extending the range of wavelengths over which light can drivephotosynthesis, and they act to protect the chlorophyllous pigments fromthe harmful photodestructive reaction which occurs in the presence ofoxygen.

Plant Pigments and Their Roles in Promoting Health

Theaccessory pigment role is a singlet-singlet energy transfer from thecarotenoid to the bacteriochlorophyll, while the protective role is atriplet-triplet energy transfer from the bacteriochlorophyll to thecarotenoid.
