The major pigments in chloroplasts are chlorophylls and carotenoids.
the outer electrons which are weakly attracte towards nucleus of a pigment can absorb a photon and gets exited to its unstable higher levels. It releases more energy when it gets stabilized to its normal state. This energy can be trapped by the electron of next pigment molecules. In this way the energy gets transfered from one to other.
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
No, grey hair is not considered dead hair. Grey hair occurs when the pigment cells in hair follicles stop producing melanin, the pigment that gives hair its color. This change in pigment production is a natural part of the aging process and does not mean that the hair is dead.
Eggs change color when heated because the protein molecules aggregate and become insoluble. Normally, the white of an egg is clear because the proteins are dissolved in water. However, when the egg is cooked, these proteins aggregate, or stick to proteins around them. These agglomerated proteins block the light differently and change the color of the egg.
Millon's solution detects phenolic compounds, which includes proteins and some non-proteins. Phenolic compounds are classified as having a hydroxyl group, or an OH, bonded directly to a hydrocarbon.
Yes. Photosynthesis involves the transfer of electrons. Photosynthesis causes a chemical change. All chemical changes involve either the transfer of electrons or a change in the configuration of electrons. No other way exists to make a chemical change.
electrons from one reactant to another, resulting in a change in oxidation states of the elements involved. The reactant that loses electrons is oxidized, while the reactant that gains electrons is reduced. This transfer of electrons is essential for the balancing of charges and the formation of new chemical bonds.

They involve either transfer of electrons, or a change in the oxidation state of some atoms involved.
A redox reaction is a chemical reaction in which one substance loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons leads to a change in the oxidation states of the substances involved.
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
They are born with pigment.
no. it is not a physical change because it is still hair. It did not change the DNA. But, if the question was if the pigment change was physical, then it would be because the pigment changed in order for the hair to be a lighter color.
if oxidation states change, it is a redox reaction
Electrons are transferred from one reactant (reducing agent) to another (oxidizing agent). The reducing agent loses electrons (oxidation) and the oxidizing agent gains electrons (reduction). This electron transfer results in the generation of electrical energy or a chemical change in the substances involved in the reaction.
In the succinate-fumarate step, electrons are transferred from succinate to FAD to form FADH2, which eventually reduces quinone to quinol. This reduction reaction leads to a color change in DPIP, indicating the transfer of electrons from succinate to the electron transport chain.
