What are the light catching membranes on a chloroplast?
it is the thylakoids
Where does the light reaction happens?
Light reactions occur in the cells chloroplast
Where in the chloroplast do light reactions occur?
The Light Dependant Reactions of photosynthesis occur on the thylakoid membranes of the chloroplast.
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 a thylakoid?
The thylakoid space is the lumenal space bound by the membrane of the thylakoid organelle in a chloroplast. The thylakoid membranes lining the space contains pigments that absorb light to perform photosynthesis.
The light-harvesting complexes of photosynthesis are located?
within the thylakoid membranes. ramon C.
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 describes the cluster of chlorophyll and other molecules in a thylakoid that help to harvest light energy during photosynthesis?
Photosystem
Are they autotrophic or heterotrophic?
Euglena is known to function as an Autotroph when light is available, while when theres no light, it hunts for food and engulfs it by phagocytosis.. It has light harvesting complexes and also protusive ability in its plasma membrane to engulf food particles.
What are the light catching membranes on a chloroplast?
it is the thylakoids
Where does the light reaction happens?
Light reactions occur in the cells chloroplast
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.
Where does the Light (dependent) reaction take place?
The light dependent reaction take place in the thylakoid of the chloroplast
In which structure of chloroplast do the light-dependent reactions occur?
The light reactions occur in the thylakoid space, which can also be called the granum.
Where is the light reaction?
On thylakoid membranes
Where in the chloroplast do light reactions occur?
The Light Dependant Reactions of photosynthesis occur on the thylakoid membranes of the chloroplast.
What in plants take in light?
Within the photosynthetic organelle called the chloroplast, there are stacks of thylakoids shaped like discs (entire stacks are known as grana). And we know that the two stages of photosynthesis, which are the Light Reactions and the Calvin Cycle, take place in the chloroplast. There are photosystems embedded in the thylakoid membranes. The photosystem is composed of a protein complex called a raction-center complex surrounded by light-harvesting complexes which contain the chlorophyll pigments and carotenoids responsible for absorbing photons of various wavelengths (depending on the pigments present in the particular plant species). In essence, the chloroplasts take in light.
