Photosynthesis is a physio-chemical process carried out by photo-auto-lithotrophs by converting light energy into chemical energy. Among the endless diversity of living organisms in the world, producers are a unique breed.Unlike consumers (herbivores, carnivores, omnivores, or decomposers) that rely ...

A model for the photochemical steps in photosynthesis is described in which only one type of reaction center participates in the chemical conversion of excitation energy. Two types of energy-collecting pigment systems can occur, but in distinction to most current models the energy is delivered to ...

Photosynthesis converts solar energy to chemical energy by means of two large pigment-protein complexes: photosystem I (PSI) and photosystem II (PSII). In higher plants, the PSI core is surrounded by a large light-harvesting complex I (LHCI) that captures sunlight and transfers the excitation ...

This stage is responsible for the conversion of sunlight into chemical energy in the form of ATP and NADPH. The light-independent reaction, also known as the Calvin Cycle, takes place in the stroma of chloroplasts. This stage uses the ATP and NADPH produced during the light-dependent reaction...
