Pheophytin or phaeophytin (abbreviated Pheo) is a chemical compound that serves as the firstelectron carrier intermediate in the electron transfer pathway of photosystem II (PS II) inplants, and the photosynthetic reaction center (RC P870) found in purple bacteria. In both PS II and RC P870, light drives electrons from the reaction center through pheophytin, which then passes the electrons to a quinone (QA) in RC P870 and RC P680. The overall mechanisms, roles, and purposes of the pheophytin molecules in the two transport chains are analogous to each other.

What is the colour of phaeophytin pigment?
Phaeophytin is a brown or olive-green pigment that is derived from chlorophyll. It is formed when chlorophyll loses its central magnesium ion, resulting in a pigment that plays a role in photosynthesis by participating in the transfer of electrons. The color can vary slightly depending on the specific conditions and the presence of other pigments.
What do thylakoids contain?
The thylakoid membrane of green plants contains 6 different pigments: Carotene - an orange pigment Xanthophyll - a yellow pigment Phaeophytin a - a gray-brown pigment Phaeophytin b - a yellow-brown pigment Chlorophyll a - a blue-green pigment Chlorophyll b- a yellow-green pigment Chlorophyll a is the most common of these 6 pigments (present in all photosynthetic plants).
What type of reaction occurs when chlorophyll breaks down into new substances?
The breakdown of chlorophyll involves a chemical reaction known as decomposition, where chlorophyll molecules are broken down into simpler substances. This process is catalyzed by enzymes and can result in the formation of new compounds such as phytol and phaeophytin.
What photosynthetic pigment is essential for the process of photosynthesis to occur?
One or more of these known pigments is required to capture the energy of light and drive photosynthesis: Chlorophyll, Xanthophyll, Carotene, Phaeophytin, Phycobilin, Bacteriochlorophyll or Bacteriorhodopsin.
Does eye color determine color blindness?
No, eye color does not determine color blindness. Color blindness is a genetic condition caused by abnormalities in the cones of the retina that detect color, and it can affect people of any eye color.
What pigments do thylakoids?
The thylakoid membrane of green plants contains 6 different pigments: Carotene - an orange pigment Xanthophyll - a yellow pigment Phaeophytin a - a gray-brown pigment Phaeophytin b - a yellow-brown pigment Chlorophyll a - a blue-green pigment Chlorophyll b- a yellow-green pigment Chlorophyll a is the most common of these 6 pigments (present in all photosynthetic plants).
What is the primary light absorbing pigment found in plants?
The chlorophyll absorbs most of the colors in the color spectrum, and reflects only green and yellow wavelengths. This is why we see leaves as green or yellow- because these colors are reflected into our eyes.
What do thylakoids contain?
The thylakoid membrane of green plants contains 6 different pigments: Carotene - an orange pigment Xanthophyll - a yellow pigment Phaeophytin a - a gray-brown pigment Phaeophytin b - a yellow-brown pigment Chlorophyll a - a blue-green pigment Chlorophyll b- a yellow-green pigment Chlorophyll a is the most common of these 6 pigments (present in all photosynthetic plants).

What are the yellow accessory pigments sometimes found in leaves called?
The yellow accessory pigments found in leaves are called carotenoids. They help plants capture light energy for photosynthesis and also contribute to the yellow, orange, and red colors of leaves in the fall.

What is the job market for acting?
yes acting is hard, if we are talking about the good acting (well yes its hard), but if we are talking about the sloopy acting of course its easy. for acting you have to have a lot of concentration and you have to know a lot of basic things that most of the people that take classes of acting and that they are professional actors do bnot know. some of you people wont know what blocking a scene is, or maybe you guys dont know that you have to mantaing a balance on scene, also you have to know about diction and other stuff to, acting is not all about you learn your lines you do your part good and evreybody gives you a round of applusse. no an actor is much more thatn that. i know cause i am an actor and most of the people that i know that call themselves actor do not know some of thoose basic stuff.
