Key Concepts

Photosynthesis

Photosynthesis is the biological process by which green plants, algae, and some bacteria convert light energy into chemical energy. This process primarily occurs in chloroplasts, where light energy is captured and used to convert carbon dioxide and water into glucose and oxygen. The light-dependent reactions of photosynthesis involve an electron transport chain that generates ATP, which is essential for various cellular functions.

Electron Transport Chain (ETC)

The electron transport chain is a series of protein complexes and other molecules located in the inner mitochondrial membrane (in eukaryotes) or the plasma membrane (in prokaryotes). It plays a crucial role in cellular respiration and photosynthesis by transferring electrons from electron donors to electron acceptors through redox reactions. This process creates a proton gradient that drives ATP synthesis via ATP synthase.

ATP (Adenosine Triphosphate)

Adenosine triphosphate (ATP) is the primary energy carrier in all living organisms. It consists of an adenosine molecule bonded to three phosphate groups, and its high-energy bonds store energy that can be released for cellular processes. ATP is produced during cellular respiration and photosynthesis, serving as a vital energy source for metabolic activities, muscle contraction, and other essential functions.
