Photosynthesis: steps, types & importance

Microbiology Notes · 4 min read · Preview summary, not a migrated article

Overview

Photosynthesis converts light energy into chemical energy. In oxygenic photosynthesis, water supplies electrons and oxygen is released. Cyanobacteria carry out oxygenic photosynthesis, whereas many other photosynthetic bacteria use different electron donors.

Key principles

Light-dependent reactions generate ATP and reducing power. Carbon fixation then incorporates inorganic carbon into organic molecules. Anoxygenic photosynthesis does not release oxygen; its electron donors can include reduced sulfur compounds.
