Light Dependent Reactions Class 11 | Cyclic & Non-Cyclic Photophosphorylation | Biology New Book

Light dependent reactions of photosynthesis, cyclic photophosphorylation, and non-cyclic photophosphorylation explained in detail for Class 11 Biology (FSc/NEET/MCAT). This lecture covers the mechanism of ATP and NADPH production during light reactions, the role of photosystem I and photosystem II, electron transport chain (ETC), chemiosmosis, and proton gradient formation. You will learn: Steps of light dependent reactions in photosynthesis Cyclic photophosphorylation (PS I only, ATP production) Non-cyclic photophosphorylation (PS I & PS II, ATP + NADPH) Role of electron carriers (plastoquinone, plastocyanin, ferredoxin, cytochrome complex) Difference between cyclic and non-cyclic photophosphorylation Importance of light reactions in bioenergetics This video is perfect for: Class 11 Biology (FSc Part 1, New Syllabus 2025) NEET & MCAT Biology preparation Students learning photosynthesis mechanisms and bioenergetics #LightDependentReactions #Class11Biology #Photophosphorylation #CyclicPhotophosphorylation #NonCyclicPhotophosphorylation #Photosynthesis #FScBiology #NEETBiology #MCATBiology #PhotosystemI #PhotosystemII #Bioenergetics #ElectronTransportChain #ATPProduction #BiologyLecture #ilmEBiology
