What is Linear Electron Transport?

Introduction

  • Linear electron transport is a series of reactions during the light-dependent stage of photosynthesis where excited electrons move through an electron transport chain, generating ATP and NADPH as energy-rich molecules, and creating a proton gradient across the thylakoid membrane to drive ATP synthesis via ATP synthase.
  • Happens in the thylakoid membrane of the chloroplasts and occurs in the presence of sunlight.
  • Involves a number of protein complexes that collaborate to transport electrons, including as Photosystem II (PSII), the Cytochrome b6f complex, and Photosystem I (PSI).
  • In order to produce ATP, NADPH, and other compounds required for the production of organic molecules during photosynthesis, L.E.T is essential for catching light energy.
