photosystem

Examples of photosystem in the following topics:

• The Two Parts of Photosynthesis

  • Two types of photosystems are embedded in the thylakoid membrane: photosystem II ( PSII) and photosystem I (PSI).
  • Each photosystem plays a key role in capturing the energy from sunlight by exciting electrons.
  • Photosystems consist of a light-harvesting complex and a reaction center.
  • In photosystem I, the electron comes from the chloroplast electron transport chain.
  • As explained above, the photosystems manipulate electrons with energy harvested from light.

• Processes of the Light-Dependent Reactions

  • Light energy is converted into chemical energy in a multiprotein complex called a photosystem.
  • Two types of photosystems, photosystem I (PSI) and photosystem II (PSII), are found in the thylakoid membrane inside the chloroplast .
  • The light-dependent reactions begin in photosystem II .
  • A photosystem consists of a light-harvesting complex and a reaction center.
  • In (b) photosystem I, the electron comes from the chloroplast electron transport chain.
