Why is coffee brown?
Coffee is brown because of a pigment known as a "tannin". The same pigment is responsible for the staining of carpet when coffee is spilled and for staining teeth when drinking coffee.
What pigment is released when a hemoglobin molecule is broken apart?
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.
What is the main pigment molecule in a green leaf?
Chlorophyll
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
Energy is transferred from pigment molecule to pigment molecule in the protein complex through resonance energy transfer, leading to excitation of a special chlorophyll a molecule called P680. This excitation of P680 causes the release of an electron, which is then transferred to the primary electron acceptor, initiating the electron transport chain in photosynthesis.
What is the function of metal in respiratory pigment?
The metal component of a respiratory pigment is the part that actually binds to the oxygen molecule.
What is the pigement?
Pigment is a molecule that absorbs light -Sasha Muy :)
What are pigments and is their function in plants?
Pigment: light-absorbing molecule.
What is the name of the pigment molecule in green plants that begins the reactions of photosynthesise?
The pigment molecule in green plants that initiates the reactions of photosynthesis is chlorophyll. Chlorophyll is a green pigment that absorbs light energy, converts it into chemical energy, and plays a key role in capturing light for photosynthesis.
How does a flavin pigment molecule work with a pH indicator?
Flavin pigment molecule can interact with a pH indicator by changing its color based on the pH of the solution. The flavin pigment undergoes a chemical reaction with the pH indicator, leading to a change in its absorption spectrum or structure, resulting in a color change that can be used to determine the pH of the solution.
What is a light-absorbing colored molecule?
A light-absorbing colored molecule is called a pigment. Pigments absorb certain wavelengths of light, causing them to appear colored. Examples include chlorophyll in plants, melanin in skin, and carotenoids in fruits and vegetables.
A molecule that contains atoms enabling it to reflect light is called a pigment?
Actually, a pigment is a molecule that selectively absorbs certain wavelengths of light, resulting in the perception of color by reflecting or transmitting other wavelengths. Pigments are responsible for the color of many living organisms, including plants, animals, and microorganisms.
What specialized pigment molecule found at the center of every photosystem unit is absolutely essential to photosynthesis?
Chlorophyll A :)
