Rotenone (an insecticide) blocks the protein that accepts
ele
ctrons from NADH. Rotenone
blocks ATP synthesis by:
Homework Answers
1. Rotenone inhibits the reduction of the NADH of the complex l in electron tranport chain.
If electrons are passed through all electron carriers ( complex I , II, III, IV then protons are translocated across the membrane and these protons try to pass through the membrane according to concentration gradient through complex V (ATP Synthase) then energy is luberatef which combines ADP and Pi to form ATP.
