What is the role of antenna molecules?
They are involved in the absorption of light, energy distribution amongst photosystems, and photoprotection. Answer: Antenna molecules in photosynthesis complexes include proteins, pigments, and chlorophylls such as carotenoids, xanthophylls, and chlorophyll b.
What are the antenna pigment molecules?
Solution : The pigment molecules (accessory pigments) surrounding the reaction centre of chlorophyll molecule which absorb and transmit the solar energy to the reaction centre are called antenna pigments e.g ., Chl-a , Chl-b Carotenoids etc.
What is the function of the antenna proteins in photosynthesis?
They are situated inside the chloroplasts of photosynthetic organisms, capture the energy from light, and transfer it to the reaction centre where chemical reactions take place.
What is the role of chlorophyll and the antenna pigments in photosynthesis?
A pigment with the primary function of capturing the energy from photons and transferring that energy to other pigments within the photosystem. Most chlorophyll molecules function as antennae, with relatively few of the hundreds of chlorophyll molecules carrying out photochemistry in the reaction center.
How do the antennae pigments help to make photosynthesis more efficient?
(a) The pigments in the antennae molecule help in making photosynthesis more efficient by absorbing different wavelengths of light.
What is the main role of the pigment molecules quizlet?
What is the main role of the pigment molecules? Absorb photons and transfer light energy to the reaction center chlorophyll. The rate of photosynthesis is much greater in the green than red light spectrum.
What is antenna molecules in photosynthesis?
The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
How is energy transferred among antenna pigment molecules?
Pigments organised into an antenna structure will transfer light energy via resonance to the reaction center, where: An excited electron is transferred to an electron acceptor. The reduction of the electron acceptor completes the transformation of light energy to: Chemical energy.
What is the main role of pigment molecule?
What is the main role of the pigment molecules? Absorb photons and transfer light energy to the reaction center chlorophyll. The rate of photosynthesis is much greater in the green than red light spectrum.
What is the main role of the pigment molecules in photosynthesis?
The importance of pigment in photosynthesis is that it helps absorb the energy from light. The free electrons at the molecular level in the chemical structure of these photosynthetic pigments revolve at certain energy levels.
What is the role of antennae molecules in light-harvesting complex 11?
Answer: They provide a wider range of wavelength of light to chlorophyll a molecule.
What is the main pigment used in photosynthesis?
Chlorophyll Photosynthetic cells contain special pigments that absorb light energy. Different pigments respond to different wavelengths of visible light. Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
What role do pigments play in the photosynthesis process?
Explanation. The pigments found in plants play an essential role in photosynthesis. These pigments, particularly the chlorophyll, capture the sun's energy. Without these pigments, photosynthesis would not occur.
What is the main role of the pigment chlorophyll?
Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.
What is the function of pigment?
The primary function of pigments in plants is photosynthesis, which uses the green pigment chlorophyll and several colorful pigments that absorb as much light energy as possible.
What is antenna in photosynthesis Class 11?
1 Answer. Antennae refers to all the pigments of the photosystem except the pigment molecule (Chl'a') that forms the reaction centre.
What are the three main pigments used in photosynthesis?
In the diagram below, you can see the absorption spectra of three key pigments in photosynthesis: chlorophyll a, chlorophyll b, and β-carotene. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color.
What is the importance of pigments in plants?
Plant pigments are important in controlling photosynthesis, growth and development of plants (Sudhakar et al., 2016). Pigments act as visible signals to attract insects, birds and animals for pollination and seed dispersal. Pigments also protect plants from damage caused by UV and visible light (Tanaka et al., 2008).
What role do pigments play in the process of photosynthesis quizlet?
Explanation. The pigments found in plants play an essential role in photosynthesis. These pigments, particularly the chlorophyll, capture the sun's energy. Without these pigments, photosynthesis would not occur.
What is the role of pigments in photosynthesis?
Photosynthetic pigments are the molecules responsible for absorbing electromagnetic radiation, transferring the energy of the absorbed photons to the reaction center, and for photochemical conversion in the photosynthetic systems of organisms capable of photosynthesis.
What is the role of pigment molecules in photosynthesis?
Photosynthetic pigments are the molecules responsible for absorbing electromagnetic radiation, transferring the energy of the absorbed photons to the reaction center, and for photochemical conversion in the photosynthetic systems of organisms capable of photosynthesis.
What is the function of pigment system in photosynthesis?
Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs –organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.
What role do pigments play in photosynthesis pigments?
Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs –organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.
What is the function of pigments in a chloroplast?
Chlorophyll and carotenoid are chloroplast pigments which are bound non-covalently to protein as pigment-protein complex and play a vital role in photosynthesis. Their functions include light harvesting, energy transfer, photochemical redox reaction, as well as photoprotection.
What is the main job of chloroplast pigments during photosynthesis?
Chlorophyll and carotenoid are chloroplast pigments which are bound non-covalently to protein as pigment-protein complex and play a vital role in photosynthesis. Their functions include light harvesting, energy transfer, photochemical redox reaction, as well as photoprotection.
What is the main role of the pigment molecules?
What is the main role of the pigment molecules? Absorb photons and transfer light energy to the reaction center chlorophyll. The rate of photosynthesis is much greater in the green than red light spectrum.
What is the main function of pigments?
Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear "colorful". Flowers, corals, and even animal skin contain pigments which give them their colors. More important than their reflection of light is the ability of pigments to absorb certain wavelengths.
