Respiration In Plants Ques 25
25. Where is the respiratory electron transport system (ETS) located in plants ?
(a) Intermembrane space
(b) Mitochondrial matrix
(c) Outer mitochondrial membrane
(d) Inner mitochondrial membrane
Show Answer
Answer : d
Hints & Solutions
(d) Electron transport system is located in inner mitochondrial membrane, where it serves as the site of oxidative phosphorylation through the action of ATP synthase. Electron transport chains are redox reactions that transfer electrons from an electron donor to an electron acceptor. The transfer of electrons is coupled to the translocation of protons across a membrane, producing a proton gradient. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes.
