Cyclic, pseudocyclic and noncyclic photophosphorylation: new links in the chain.
Photosynthetic electron transport is coupled to ATP synthesis. This process - photosynthetic phosphorylation - proceeds by several alternative electron-transport pathways in isolated chloroplasts. The question: 'Which of these works in real life?' has long occupied students of photosynthesis. Recent results from structural biology and genomics suggest that the answer is 'All of them'. The interplay between the pathways might explain the flexibility of photosynthesis in meeting different metabolic demands for ATP.
