What is photosystems?
The group of proteins and pigments that transfers electrons to reaction center
Do plants have adaptations that maximise light absorbsion?
One of the main adaptions is the range of pigments that absorb the light in plants. From the standard P680 and P700 pigments ( named for the absorption spectrum, in nanometers, they pick up in ) in the two photosystems to many different pigments in the array of pigments surrounding the reaction center. These pigments absorb light outside the red and blue range and they become visible when the leaves of plants turn colors in the fall.
What are the products of the light reaction and how they formed?
ydrogen (in the form of NADPH). Both are formed when the water molecule is split by photons of light in the photosystems of the light reaction.
What is a series of reactions that involve pigments?
A series of reactions that involve pigments is photosynthesis.
What is the difference between a reactant and a catalyst?
A reactant is consumed in a reaction to make products. A catalyst is not consumed during the reaction. It is either not directly involved in the reaction or regenerated upon the end of the reaction. This is the main difference. In addition, catalysts work by decreasing the activation energy for the reaction, allowing the reactants to react more easily.

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.
Are photosystems 1 and 2 found in the Calvin cycle?
They are found in the light reaction. Photosystems not involved in Calvin cycle.
What is the series of reactions that involve pigments?
The series of reactions that involve pigments is called light reaction. It is defined as the reaction of something, especially the iris of the eye, to different intensities of light.
How is light reaction of photosynthesis started?
Absorbtion of light by photosystems in cyclic and non-cyclic photophosphorylation.
What are the products of the light reaction and how they formed?
ydrogen (in the form of NADPH). Both are formed when the water molecule is split by photons of light in the photosystems of the light reaction.
Lab 4 AP Bio Plant Pigments and Photosynthesis?
Photosynthesis is a light reaction that happen in the chloroplast by wavelenght types
What is the first site of photosynthesis in chloroplast?
First reaction is light reaction.It takes place in photosystems of thylacoid membrane.
What is a series of reactions that involve pigments?
A series of reactions that involve pigments is photosynthesis.
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.
