Which is the best description of Photophosphorylation?

Which is the best description of Photophosphorylation?

Answer Expert Verified. Photophosphorylation is a process that occurs during photosynthesis in plants. It is the conversion of ADP (Adenosine Diphosphate) into ATP (Adenosine Triphosphate) using light energy. ATP (Adenosine Triphosphate) is the energy currency of life of all living organisms.

What wavelength of light is best absorbed by chlorophyll A?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Which Colour of light is minimum absorbed by chlorophyll?

green light

Which of the colors absorbed by chlorophyll A is least visible?

blue light

Which of the colors is absorbed by chlorophyll the second most?

For example, the green-yellow color of a leaf is due to a pigment in the leaf called chlorophyll. When white light (which contains all of the colors of the spectrum) shines on chlorophyll, the chlorophyll absorbs most of the red, orange, blue, and violet, and it reflects most of the green and yellow.

Which of the colors absorbed by chlorophyll is most visible?

chlorophyll absorbs most of the red, orange, blue, and violet and reflects most of the green and yellow. That is why you see a yellow-green color. Think of a pigment as a sponge that soaks up all of the other colors of the spectrum except the one you see.

What 2 colors are best absorbed by chlorophyll a what 2 colors are best reflected by chlorophyll A?

Chlorophyll a absorbs light in the blue-violet region, chlorophyll b absorbs red-blue light, and both a and b reflect green light (which is why chlorophyll appears green).

Why Chlorophyll absorbs blue and red light?

Short answer: plant absorbs mostly “blue” and “red” light. To do this, plants have pigment molecules which absorb the energy of light very well. The pigment responsible for Page 7 most light-harvesting by plants is chlorophyll, a green pigment.

What is the Colour of chlorophyll A?

green

What color absorbs Xanthophyll?

Xanthophylls are yellow-brown pigments that absorb blue light.

Does Xanthophyll absorb red light?

Xanthophylls and carotenes absorb wavelengths of light that chlorophylls cannot absorb. Carotenoids absorb light in the blue-green and violet region and reflect the longer yellow, red, and orange wavelengths; these pigments also dispose excess energy out of the cell.

Does Xanthophyll absorb green light?

Blue-green. The plant pigment xanthophyll absorbs light in the range of 400 – 550 nm and reflects the other wavelengths. The xanthophyll cycle involves conversions of pigments from a non-energy-quenching form to energy-quenching forms.

At what wavelength does Xanthophyll absorb?

494 nm

What wavelength does B carotene absorb?

The absorption spectrum of β-carotene (a carotenoid pigment) includes violet and blue-green light, as is indicated by its peaks at around 450 and 475 nm. Most photosynthetic organisms have a variety of different pigments, so they can absorb energy from a wide range of wavelengths.

Why is white light the best for photosynthesis?

White light is the most effective light for photosynthesis because it provides a wide range of colored lights for various pigments to use. When only a single color is used, red is the most effective color of light.
