How is ATP synthesis in photosynthesis different from that of respiration?
Answer
In photosynthesis, ATP is synthesized via phosphorylation in the presence of light, primarily using the electron transport chain in the thylakoid membrane. In respiration, ATP is synthesized through oxidative phosphorylation in the mitochondria during aerobic respiration. The main difference lies in the source of energy: light for photosynthesis and chemical bonds (glucose) for respiration.
