WebPhosphorylation is the addition of a phosphoryl (PO 3) group to a molecule. In biological systems, this reaction is vital for the cellular storage and transfer of free energy using energy carrier molecules. Adenosine 5’-triphosphate (ATP), the most abundant energy carrier molecule, has two high-energy phosphate‑phosphate bonds that can be ... WebH+ also joins, forming water – a product of respiration.

WebSubstrate-level phosphorylation A phosphate is transferred from one of the intermediates to ADP, forming 1 ATP Exam Tip The Krebs cycle is often referred to as cyclical or circular. This is because the acceptor molecule oxaloacetate is regenerated throughout the reaction so that it can start all over again by adding another acetyl CoA. WebPhotosynthesis occurs in two stages: the light-dependent stage, which takes place in the thylakoids, and the light-independent stage, which takes place in the stroma. Light energy is used to breakdown water (photolysis) to produce hydrogen ions, electrons and oxygen in the thylakoid lumen. A proton gradient is formed due to the photolysis of ...
