How does chemiosmosis function in bioenergetics? Chemiosmosis is the movement of hydrogen ions across a selectively permiable membrane. this generates ATP when ithe ions are moved during cellular respiration or photosynthesis. Chemiosmosis is essential in ATP production in eukariotic and some prokaryotic cells.

How are organic molecules broken down?

The breaking down of complex organic molecules occurs via catabolic pathways and usually involves the release of energy. Through catabolic pathways, polymers such as proteins, nucleic acids, and polysaccharides are reduced to their constituent parts: amino acids, nucleotides, and sugars, respectively.

How is chemiosmosis used in cellular respiration?

During cellular respiration, protons (H⁺) travel down a proton gradient by chemiosmosis. This causes the enzyme ATP synthase to turn and join a phosphate group to adenosine diphosphate (ADP), forming ATP.
