Photosynthesis and Plant Physiology: From Light Reactions to CAM

Understanding how light transforms into chemical energy is fundamental to mastering biology and plant sciences. This course offers a clear, structured guide to the biochemical mechanisms behind photosynthesis. You will gain a thorough conceptual understanding of how plants, algae, and bacteria capture solar energy to fuel life on Earth. What you'll learn: - Understand the fundamental terminology, historical experiments, and structural biology of chloroplasts - Analyze the light-dependent reactions, including cyclic and non-cyclic photophosphorylation - Explore the dark reactions (Calvin cycle) and the synthesis of organic molecules - Compare C3, C4, and Crassulacean Acid Metabolism (CAM) pathways and their ecological significance - Examine photorespiration and how environmental factors limit photosynthetic efficiency - Discover the mechanisms of bacterial photosynthesis and how they differ from plant systems - Investigate modern perspectives on how changing environmental conditions affect photosynthetic efficiency The course begins with foundational concepts and early scientific discoveries before guiding you step-by-step through light and dark reactions, alternative carbon-fixing pathways, and evolutionary adaptations. Designed for beginners, biology students, and science enthusiasts, this written course requires no advanced science prerequisites.
