chemiosmotic
/ˌkɛmɪɒzˈmɒtɪk/(also chemosmotic)
adjective
Biochemistry. Of, relating to, or involving a process in which ions are translocated across a membrane to produce an electrochemical gradient, or diffuse passively down such a gradient; specifically designating a theory (now generally accepted) that energy for biochemical processes is supplied by creation of a gradient of hydrogen ion (proton) concentration across a membrane; relating to or conforming to this theory.
- The theory was proposed by Peter Mitchell to explain how the energy for oxidative phosphorylation (ATP synthesis) arose from the pumping of protons across the membranes of mitochondria and chloroplasts, coupled with electron transport within the membranes..
Origin
Late 19th century (in an earlier sense). From chemiosmosis, originally after German chemosmotisch.
