Light dependent reactions

This comprehensive overview explores light-dependent reactions, light-independent reactions, alternate pathways like CO2 fixation, glycolysis, fermentation, Krebs Cycle, and more. Discover the intricate processes and connections between these fundamental biochemical pathways. Learn about the production of ATP and NADPH in light reactions, the requirements and phases of the Calvin Cycle in dark reactions, and the distinctions between C3 and C4 plants. Expand your knowledge on the ATP-generating pathways and the significance of each step in energy production through this illuminating exploration of photosynthesis and cellular respiration.
