ATP Synthesis

ATP is synthesised by the enzyme ATP synthase in a condensation reaction.ADP + Pi + energy → ATP + H2OThe reaction is called phosphorylation and ATP synthesis is the reverse of the hydrolysis reaction.ATP is synthesised in plant and animal cells during processes called phosphorylation.Photophosphorylation occurs during photosynthesis.Oxidative phosphorylation occurs during respiration.Substrate level phosphorylation occurs when phosphate groups from molecules are transferred to ADP.
