What is the main role of pigment molecules within the antenna or light harvesting complex?
The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
What is the cluster of light harvesting complexes in a thylakoid?
photosystem(s)
What is composed of a light-harvesting complex and an electron transport system?
The chloroplast
What are the energy carrying end products of the light harvesting reactions?
NADPH and ATP
What is phase cropping?
is a system of continous croppig and harvesting
Antennalike energy-harvesting unit in a thylakoid?
Antenna pigments, chlorophyll a, chlorophyll b, and carotenoids, that are light harvesting antennas in the thylakoid. After the antenna pigments absorb light energy and transformed as chemical energy then transfered to the reaction center complex.
What is the main role of pigment molecules within the antenna or light harvesting complex?
The light-harvesting (or antenna) complex of plants is an array of protein and chlorophyll molecules embedded in the thylakoid membrane which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
What is light harvesting?
light harvesting is a set of photosynthetic pigment molecules that absorb light and channel the energy to the photosynthetic reaction centre, where the light reactions of photosynthesis occur.
What happens after the reaction center receives energy from molecules in the light harvesting complex?
It passes the energy to the reaction center ( a specialized region of photosystem) then the energized electrons leave the reaction centers and are passed to adjacent electron transport chains (ETC)
What is the cluster of light harvesting complexes in a thylakoid?
photosystem(s)
In photosynthesis what is another name for a light harvesting complex?
The cytochrome systems.
What energy carrying end products of the light harvesting reactions?
ATP
What are the energy-carrying end products of the light harvesting products?
ATP
What is composed of a light-harvesting complex and an electron transport system?
The chloroplast
What is phycocyanin?
Phycocyanin is a pigment from the light-harvesting phycobiliprotein family. It is in some algae and bacteria that absorb light in the 618 nm range.
What are photosystems made of?
In the thylakoid membrane a number of light-harvesting complexes and a reaction center complex. The chlorophyll a molecule at the reaction center of photosystem II is called P680. At the reaction center of photosystem I is a chlorophyll a molecule called P700.
The light-harvesting complexes of photosynthesis are located?
within the thylakoid membranes. ramon C.
