Q:What are the ingredients in MAC's pigments? (10pts)?
Mac Pigment Ingredients
Q:Where about in the beetroot is the pigment concentrated more?
I've known it to be in the skin and thats from a cooking point of view.
Q:explain an absorption spectrum of different pigments and the action spectrum of?
Emission spectra is considered whilst a gas, as an occasion, is heated. The electrons of its atoms are excited and can ultimately substitute its potential point. this occasion being volatile, the electron ultimately returns to the preliminary state and emits a nicely-defined photon. In an absorption spectra the source of sunshine isn't the gas. An exterior source of white (or however variety you want) easy emits in direction of the gas you're utilising; on condition that the potential ranges are quantified on the atoms of the gas, the electrons of the atoms would be excited in basic terms whilst a photon of precise potential (akin to the potential difference between the electron's point and yet another one on the atom) arrives. hence, based on the gas, in basic terms nicely-defined photons would be absorbed, and the absorption spectra is then obtained.
Q:What happens to the yellow pigments in a leaf during the summer months?
in case you may surely ask a query like that, then it sounds to me such as you opt to have intercourse with one in all your instructors. enable me be the 1st to tell you that it will no longer take place! She's/he's have been given a husband/spouse to do each and all the grimy paintings for her/him! you're basically a pupil and that's a criminal offense in each and each state for a instructor to have something for a minor! Have had a weigh down on a instructor, definite that's a load of bull-****, yet that's the way life is and we the two might desire to provide up dreaming and locate ourselves a hoe which will please us in each way conceivable! that's effective to appreciate that somebody else has wandered that. % me as suited answer on account which you and that i've got lots in worry-loose!
Q:What pigments take part in photosynthesis?
Photosynthesis in plants is dependent upon capturing light energy in the pigment chlorophyll.This chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range - that would make the leaves black! Some plants and plantlike organisms have developed other pigments to compensate for low light or poor use of light. Cyanobacteria and red algae have phycocyanin and allophycocyanin as accessory pigments to absorbe orange light. They also have a red pigment called phycoerythrin that absorbs green light and extends the range of photosynthesis. The red pigment lycopene is found in vegetables. Some red algae are in fact nearly black, so that increases their photosynthetic efficiency. Brown algae have the pigment fucoxanthin in addition to chlorophyll to widen their absorption range.
Q:do all leaves extract contain the same pigments??why?
Absolutely not. Leaf pigments, just to name a few, may include chlorophyll, carotenes, lutein, anthocyanins. Not only will pigment content vary between plant species, but pigment content will vary in individual plants seasonally.
Q:Explain light activation of pigments (absorption of light by pigments)?
A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.
Q:What is a pigment?????????!?
Melanin (i /ˈmɛlənɪn/; Greek: μέλας, black) is a pigment that is ubiquitous in nature, being found in most organisms (spiders are one of the few groups in which it has not been detected). In animals melanin pigments are derivatives of the amino acid tyrosine. The most common form of biological melanin is eumelanin, a brown-black polymer of dihydroxyindole carboxylic acids, and their reduced forms. All melanins are derivatives of polyacetylene. The most common melanin – dopamelanin – is a mixed copolymer of polyacetylene, polyaniline, and polypyrrole. Another common form of melanin is pheomelanin, a red-brown polymer of benzothiazine units largely responsible for red hair and freckles. The presence of melanin in the archaea and bacteria kingdoms is an issue of ongoing debate among researchers in the field. The increased production of melanin in human skin is called melanogenesis. Production of melanin is stimulated by DNA damage induced by UVB-radiation,[1] and it leads to a delayed development of a tan. This melanogenesis-based tan takes more time to develop, but it is long lasting.[2] The photochemical properties of melanin make it an excellent photoprotectant. It absorbs harmful UV-radiation and transforms the energy into harmless heat through a process called ultrafast internal conversion. This property enables melanin to dissipate more than 99.9% of the absorbed UV radiation as heat[3] (see photoprotection). This prevents the indirect DNA damage that is responsible for the formation of malignant melanoma and other skin cancers. Albinism (from Latin albus, white; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin.
Q:How are plant pigments involved in photosynthesis?
Plant pigments - as other pigments - interact with light to absorb only certain wavelengths. In plants the different sorts of pigments are useful to absorb available wavelengths of light and enable photosynthesis in shadow, in bright sunshine, in deep sea etc.: each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture as much as possible of the sun's energy.
Q:Are pigments the same as tannins?
Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.
