Glucose produced during photosynthesis contains energy absorbed from sunlight. The energy released from the breakdown of glucose, is used to synthesise ATP by a process called chemiosmosis.

Key terms in this lesson
- pyruvate
- The three-carbon end product of glycolysis, which enters the mitochondrion for the link reaction in the presence of oxygen or is reduced to lactate or ethanol in its absence.
- ATP
- Adenosine triphosphate, the universal energy currency of cells, formed by adding an inorganic phosphate to ADP and hydrolysed to release energy for cellular reactions.
- chemiosmosis
- The synthesis of ATP by ATP synthase, driven by the flow of protons down their concentration gradient across a membrane.
